Abstract An unsteady two-dimensional laminar forced convection heat transfer around a square cylinder with rounded corner edge is numerically investigated for Prandtl Number, Pr=0.01–1,000 and non-dimensional corner radius, r=0.50–0.71 at low Reynolds number, Re=100. The effect of gradual transformation of square cylinder into circular cylinder on heat transfer phenomenon is studied. The lateral sides of the computational domain are kept constant to maintain the blockage as 5 %. A structured non-uniform mesh is used for the computational domain and the Finite Volume Method (FVM) based commercial software Ansys FLUENT is used for numerical simulation. The heat transfer characteristics over the rounded corner square cylinder are analyzed with the isotherm patterns, local Nusselt number (Nulocal), average Nusselt number (Nuavg) at various Pr and various corner radii. It is found that the heat transfer rate of a circular cylinder can be enhanced 14 % by introducing a new cylinder geometry of corner radius, r=0. 51.

To ensure the safety of people’s lives and property, the accurate measurement of various small vibrations is of great significance. Using gratings as sensitive components to make optical fiber sensors is a kind of electromechanical vibration measurement device with rapid development. In this study, a special-shaped beam Fiber Bragg Grating (FBG) electromechanical vibration sensor with sensitized grooves is proposed based on equal-strength cantilever beams. The composition and implementation principle of FBG sensing system are expounded, and how to realize the signal induction of FBG under vibration conditions is further analyzed. According to the intrinsic relationship between sensitivity coefficient and natural frequency in vibration sensor, the sensor head structure composed of structural parameters, such as equal-strength beam length of 73 mm, bottom width of 14 mm, and thickness of 5 mm, is finally selected. With the help of ANSYS software to calculate the natural frequency of the sensing head as a theoretical reference value, and SS304 stainless steel is selected as the cantilever beam to obtain a good vibration sensing effect. In the test, the acceleration is set to 0.35 G, and the pulse generates a sinusoidal signal of 0–10000 Hz. The natural frequency of the sensing head is 182 Hz, and the sensitivity is 100 mV/G, which is only small error with the theoretical analysis value calculated by ANSYS. The acceleration of the sensing head is changed, and different degrees of vibration are generated. The results show that the change of output center wavelength has a linear relationship with the acceleration change. The introduction of sensitized grooved special-shaped beams helps to improve the sensitivity of the device to perceive vibration. It is used for the monitoring of the contact status of the intelligent knife switch. The results show that the designed photoelectric grating electromechanical sensor measurement has good repeatability, and the wavelength of the reflection interrogator will suddenly increase and decrease rapidly with obvious regularity.

Objectives: Calcaneal fractures are the most common tarsal fractures following a foot-ankle trauma. The Böhler’s angle is an important measurable angle before, during, and after surgery. In this study, we aimed to investigate correlation between Böhler’s angle, calcaneal strength, and subtalar joint stress using a finite element analysis (FEA). Patients and methods: Between January 2016 and December 2016, computed tomography (CT) scans were used with MIMICS® software for FEA. The ankle and foot of a 23-year-old male person with a height of 180 cm and weighing 80 kg was modeled as reference. Raw coronal CT images were obtained in Digital Imaging and Communications in Medicine format with the resolution of 512X512 pixels and 0.3-mm slice intervals in 135 kV. The structures including tibia, fibula and 26 other bones (talus, calcaneus, cuboid, navicular, three cuneiforms, five metatarsals, and 14 components of phalanges), cartilage and ligamentous tissues were modeled to form ankle joint. After determining Böhler’s angle as 35 degrees for the reference model, a fracture line was created on calcaneus. Calcaneus was remodeled with the Böhler’s angle of 45, 40, 30, 25, 20, 10, and 0 degrees respectively. All models were transferred to ANSYS software for FEA and the loads on the lower extremities with normal posture were applied on models. Results: Analysis of all models based in the reference model revealed that maximum tension values on calcaneus increased, while the Böhler’s angle decreased, indicating a statistically significant difference. The decreased Böhler’s angle indicated statistically significantly higher maximum tension values (p=0.04). Action force in subtalar joint was evaluated by comparing with the forces in reference model. The increased Böhler’s angle was found to be associated with statistically significantly decreased amount of load on subtalar joint. The decreased Böhler’s angle was related to the statistically significantly increased amount of load on subtalar joint. Conclusion: Our study results suggest that decreased Böhler’s angle increases the possibility of subtalar arthrosis, although overcorrection of the Böhler’s angle seems not to increase the risk of subtalar arthrosis.

 Global demand growth has driven the development of more inventive methods for enhancing oil well drilling at lower prices and avoiding operational issues that slow down oil well drilling. The present research is significant because the lifting capacity may be increased by inserting polymer beads into drilling mud instead of high-cost additives. The numerical cuttings trajectory simulation was performed using the commercial ANSYS FLUENT 2019 R3 software to account for the influence of cuttings collisions. To test the cuts transport behavior owing to the presence of liquid and solid phases, the (Eulerian-Eulerian) model was utilized. The mind transfer rate is determined in this simulation by varying the operating parameters (drilling mud flow rate and temperature, cuttings size and inclination, drill pipe rotation and eccentricity) with and without polyethylene (PE) beads. The result show that the average error ratio between the results of the numerical simulation is 5 % with the experimental results of researcher Ismail. The higher the percentage of PE beads entering with the drilling fluid, the lower the concentration of the cuttings within the annular space of the simulation model. The concentration of cuttings within the annular space reaches 28 % when drilling fluid flows at a speed of 1.2 m/s without adding polyethylene PE beads. While it decreases to (17, 21, 24) % when adding beads by (6, 4, 2) %, respectively, at the same flow velocity of drilling fluid. The decrease in the concentration of cuttings within the annular space of the simulation model reaches 14 % when PE beads are inserting with drilling fluid by 6 % and the drill pipe rotation speed is 0 rpm, While the percentage increases to 65 % when the drill pipe rotation speed is increased to 120 rpm at the same ratio of PE beads entering with the drilling fluid. The reduction percentage of the cuttings concentration within the annular space of the simulation model reaches 30 % when 6 % of PE beads are entered into the drilling fluid at a temperature of 20 ℃, while the percentage is reduced to 14 % when the drilling fluid temperature is 50 ℃ at the same percentage of PE beads is inserting. The inserting of polyethylene (PE) beads with the drilling fluid has increased the ability of the drilling fluid to move the cuttings, but it is affected by the amount of drilling angle, as we found that the effect of the polyethylene (PE) beads is effective and clear when the drilling angle is 0˚ (vertical). While its effect becomes less at the drilling angle of directional wells and becomes very weak at the drilling angle of 90˚ (horizontal).The inserting of polyethylene (PE) beads with drilling fluid has a good and positive effect with large-sized cuttings when compared with the impact of the beads with smaller-sized cuttings.

A simulation model is established base on ANSYS software in line with the generating mechanism of the rolling resistance, and then the analytical process of rolling resistance is present. Fourier Series is applied to fit the strain and stress, and order 31 Fourier function is chosen to fit the curves of stress and strain of each element in the rolling course of tire. 2D and 3D finite element model of a 7.00-14 16 PR bias tire is established to solve the strain and stress in a rolling cycle. The rolling resistance of 7.00-14 16 PR bias tire in the case of the rated working condition is simulated and compared with the related empirical equation. The simulation result is basically consistent with that obtained by the empirical equation. The simulation method is conducive to the structural design of tire and computation or prediction of rolling resistance of tire.

The failure of valve affects the engine performance and as a result importance is given to the failure analysis of internal combustion engine valves. The valve may fail by valve face recession, wear failure, fatigue failure, thermal fatigue, erosion / corrosion of valves, overheating of valves and carbon deposits on valves. Mostly valves fail due to high pressure and temperature. This paper presents a failure analysis of diesel engine exhaust valve used in a passenger car. The analyzed exhaust valve failed after a very short period of usage of the car. To determine the cause of failure stress analysis is carried out by finite element method which shows the highly stressed region on the valve. A proper CAD model is developed by using CATIA software and saved in 'iges' format. It is then imported into ANSYS 14 software which gives the von mises stress, strain and deformation. The stress analysis shows that maximum stress is developed near the head of valve when piston crashed to the valve and material analysis shows that the strength of valve decreases due to decarburization of material and as a result the valve was bent.

It is very important to carry out effective safety inspections on suppression rigging because of the bad service environment of suppression rigging: marine environments. In this paper, the multi-parameter simulation method in ANSYS and ANSYS Electronics Suite simulation software is used to simulate the effect of geomagnetic fields on the magnetic induction intensity of defective pressed rigging under the variable stress in marine environments. The results of the ANSYS simulation and geomagnetic flaw detection equipment are verified. The simulation results show that, according to the multi-parameter simulation results of ANSYS and ANSYS Electronics Suite simulation software, it can be found that, under the action of transverse force, the internal stress of the pressed rigging will affect the magnetic field around pressed rigging with defects. With an increase in internal stress in the range of 0~20 MPa, the magnetic induction intensity increases to 0.55 A/m, and with an increase in internal stress in the range of 20~150 MPa, the magnetic induction intensity decreases to 0.06 A/m. From the use of a force magnetic coupling analysis method, it can be obtained, under the lateral force of the defects in suppressing rigging, that magnetic flux leakage signals decrease with an increase in the rigging’s radial distance. The experiment results show that the difference between the peak and trough of the magnetic induction intensity at the pressed rigging defect calculated by the ANSYS simulation is very consistent with the results measured by the geomagnetic flaw detection equipment.

In general, the turbulent flow inside PWR (Pressurized Water Reactor) fuel assembly depends on the mixing vane configuration and the pattern of the mixing vane arrangement on the strap of the spacer grid. In this study, in order to examine the turbulent flow structure inside fuel assembly with the split-type mixing vanes, simulations were conducted with the commercial CFD (Computational Fluid Dynamics) software, ANSYS CFX R.14. Two different types of turbulence models, i.e. SAS (Scale-Adaptive Simulation)-SST (Shear Stress Transport) and DES (Detached Eddy Simulation), were used. The predicted results were compared with the measured data from the MATiS-H (Measurement and Analysis of Turbulent Mixing in Subchannels-Horizontal) test facility. Although there were locally differences between the prediction and the measurement, ANSYS CFX R.14 predicted the time averaged velocity field in the reliable level. The predicted horizontal and vertical velocity components were more in agreement with the measured data than the axial velocity component. There was no significant difference in the prediction accuracy of both turbulence models.

This study thoroughly investigates the vibration responses of fibre-reinforced laminated composite plates, focusing on identifying mode shapes and calculating natural frequencies. Theoretical calculations, based on the material properties, geometric dimensions, and boundary conditions, were performed to determine the natural frequencies at which the plate vibrates naturally under dynamic loads. A comprehensive modal analysis using ANSYS software involved creating a detailed 3D model of the composite plate with ply orientations set at 0 degrees and 90 degrees to study the effects of fibre orientation on the plate's vibration characteristics. Mode shapes, representing specific deformation patterns at each natural frequency, were identified, providing critical insights into the movement of different parts of the plate during vibration. The comparison of theoretical natural frequencies with those derived from ANSYS simulations showed a strong correlation, validating the accuracy of both the theoretical models and the ANSYS simulations. The results highlighted the natural frequencies for specific modes (Mode 11, Mode 21, and Mode 22), showing close agreement between theoretical and analytical values. This study demonstrates that theoretical models can accurately predict the natural frequencies and mode shapes of fibre-reinforced laminated composite plates. The close match between theoretical and analytical results underscores the reliability of ANSYS software for conducting modal analysis in composite materials. Identifying mode shapes and natural frequencies is crucial for designing and optimizing composite structures to withstand operational loads and dynamic forces without experiencing excessive vibrations or failures.

The objective of this study is to determine the best materials for the tibia/femoral combination of the prosthetic knee joint using commercial available FEM software. Insertion of these joints in human should not result in too much of discomfort and postoperative treatment. Further, the life and performance of the artificial joints is of prime concern. During activation, contact is established between tibia and femoral components leading to stresses at the interface, which in turn dictates the performance of these joints. The intensity of the developed stresses at the interface depends on several important factors such as the materials used for tibia/femoral components and the load acting on the bearing surfaces of the joint. To ensure reduction in the stress intensity, it is of utmost importance to select the best materials for tibia/femoral combination. In this regard, FEM the most powerful and widely accepted numerical tool to predict the state of stress is currently gaining importance in optimization of design of knee joint. In the light of the above, this paper discusses the modeling and finite element analysis of prosthetic tibia/femoral joint with different material combinations. The materials like stainless steel, titanium alloy and alumina ceramic are considered for the femoral component. Polyethylene and polyethylene chopped carbon fiber composite are considered for the tibial insert. The three dimensional model was developed using PRO E software for sagittal radius of 40 mm and 0 degree flexion angle, while load was varied from 500-2667N. An explicit finite element was generated using hyper mesh software and was solved by ANSYS. For a given load, a considerable reduction in the stress intensity at the interface of femur made of alumina ceramic and tibia made of polyethylene chopped carbon fiber composite have been observed when compared with other combinations of materials investigated.

In CFD software, the aerodynamic of VAWT can be analyzed in terms of pressure losses in the struts. The simulation method starts by making a struts model, then meshing and setting up ANSYS's boundary conditions. The last iteration runs in ANSYS until convergence. Our results show the percentage of pressure losses with the variation of the angle of wind 0°, 20°, 40°, and 60° are 0.67 %, 0.52 %, 0.48 %, and 0.52 %. The effect of triangle strut in VAWT did not affect the wind flow to the VAWT blade. The results also indicated that the triangle strut could be applied in the multi-stage of VAWT system.

In the study, a numerical simulation of the sliding properties of the rough and smooth surfaces with micro-structure was made. The simulation of shear flow in the micro-channel was performed with ANSYS FLUENT software. The 3-D and two-phase flow is simulated by choosing the volume of fluid model. In CFD analysis, water and air consist of two immiscible phases. In the calculations, if water is the first fluid and air is the second fluid, adjustments are made. At the beginning of the analysis, the channel was considered to be completely filled with air and the effect of gravity was ignored during the calculation. Water and air are considered Newtonian and incompressible fluids. In addition, laminar flow and steady-state calculations are made. It was found that the decrease in pressure drop increased with increasing distance between asperities (no-shear fraction). In the simulation results, approximately 14% of the velocity in the micro-channel axis was measured at the interface.

In this study, the finite element software ANSYS was used to analyze the mechanical behavior of local sharp-notched circular tubes under cyclic bending. The local sharp-notched depths include: 0.2, 0.4, 0.6, 0.8 and 1.0 mm, and the local sharp-notched directions include: 0, 30, 60 and 90 degrees. According to the experimental result, the notch depth has no influence on the moment-curvature relationship. But the notch depth increases, the unsymmetrical phenomenon of the ovalization-curvature relationship becomes more obvious and the speed of ovalization accelerates. In addition, the ovalization-curvature relationship becomes symmetrical when the direction angle increases. The ANSYS analysis was compared with the experimental finding. Although some differences between the experimental and simulated results, but both trends were very similar.

The dry shrinkage deformation of polypropylene fiber mortar was analyzed by ANSYS software and compared with experiment value in this paper. The error of the calculated and experimental results in the 14 days and 28 days are 7.8% and 10.5%. It can be found that the calculated results are in good agreement with test results. The results indicate that the dry shrinkage value of polypropylene fiber mortar is lower than ordinary mortar. Adding polypropylene fibers can inhibit the process of cracking and improve the fracture toughness of cement-based materials.

Parametric design language in finite element analysis software ANSYS is adopted to establish the analysis model in the construction of the 0# block of a rigid frame bridge on the pier bracket in different times, simulating the placing process of the 0# block of this bridge with three times, and analyzing and understanding the deformation and stress distribution of the bracket and 0# block during each placement of the 0# block. The load participation coefficient of the concrete placed in the 0# block in subsequent 0# block construction is obtained by the analysis and comparison of the stresses of the bracket’s longitudinal beam in the 0# block placed in one time and the 0# block placed in different times. In the meantime, the numerical calculation is proved to be reliable and correct based on the calculation of multiple software programs and the comparison of field test data. These conclusions are meaningful for the design of the bracket for multiple mass 0# block placements, load calculation, and 0# block construction monitoring.

Collisions between cars and pedestrians are one of the leading causes of death and injury in urban traffic. This study focused on analyzing the mechanism of collision between the human head and the bonnet of a car in order to identify the factors that affect the degree of injury. The research model is built on the simulation of a direct collision between the human head model and the bonnet of a car, with the collision position and contact angle following Euro NCAP experimental standards and simulated with different impact velocities. Ansys LS-DYNA software is used to simulate the collision process, in which the HIC (Head Injury Criterion) is applied to assess the degree of head injury risk based on linear acceleration at the center of mass of the head in impact experiments. Using the AIS (Abbreviated Injury Scale) system is a system that classifies the severity of injuries on a scale from 0 to 6, helping to quantify and describe the severity of injuries. The simulation results show that the HIC index increases from 168.74 at 35 km/h to 1782.56 at 80 km/h, while the probability of fatal injury (AIS-6) increases from 0 % to more than 10 %, clearly reflecting the rapid increase in danger as the speed increases. Identifying and analyzing these characteristics can help to come up with bonnet design solutions that can minimize the impact of collisions, improve car safety inspection standards, help traffic managers regulate appropriate driving speeds in urban areas, etc to improve pedestrian safety in urban environments

In this study, we apply third-order shear deformation thick shell theory to analytically derive the frequency characteristics of the free vibration of thick spherical laminated composite shells. The equations of motion are derived using Hamilton&rsquo;s principle of minimum energy and on the basis of the relationships between forces, moments, and stress displacements in the shell.
 
 We confirm the derived equations and analytical results through the finite element technique by using the well-known software packages MATLAB and ANSYS. We consider the fundamental natural frequencies and the mode shapes of simply supported spherical cross-ply (0, 90), (0, 90, 0), and (0, 90, 90, 0) laminated composite shells. Then, to increase accuracy and decrease calculation efforts, we compare the results obtained through classical theory and first-order shear deformation theory.

Currently, the improvement of methods for calculating building structures is continuing, including, among other things, methods for determining the magnitude of the load. Despite the fact that for most impacts, the principles of determining loads and methods from the application have been formed for a long time, a number of special tasks are sometimes encountered in design practice, for example, the impact of tsunami waves on a structure. This article is devoted to modeling the wave roll on a structure in the "Fluid Flow (Fluent)" module of the ANSYS 2021 software package and comparing the results obtained with the methodology presented in SP 292.1325800.2017 "Buildings and structures in tsunami-prone areas. Design rules". The studies presented in this article have shown that the nature of the propagation of hydrodynamic pressure when modeling wave rolling in ANSYS is similar to that presented in SP 292.1325800.2017: according to a triangular plot with maximum pressure at the bottom. But at the same time, the value of the maximum pressure on the joint venture is about 1.5 times greater than according to the calculation in ANSYS, which is explained by many different factors. But, despite this, modeling of the tsunami waves rolling on the construction site can be performed at the pre-project stage in order to assess the nature of the pressure distribution over the surface of the object, which will allow choosing the most suitable structural and space-planning solutions.

Объектами исследования являются подводные трубопроводы. Цель работы состоит в сравнении аналитических и численных методов расчета коэффициента теплопередачи между транспортируемым флюидом и внешней средой. Для достижения поставленной цели выполнено сопоставление коэффициентов теплопередачи, полученных как по аналитическим методикам, в том числе реализованным в ПО PIPESIM, так и путем численного моделирования процесса теплообмена в ПО Ansys Fluent и Ansys Mechanical, которое показало хорошую сходимость аналитического метода OTC 23033 с результатами численного моделирования. При решении тепловых задач в Ansys Mechanical рассмотрены два крайних случая: с граничными условиями на поверхностях трубы и грунта как в виде конвекции, соответствующей нулевой скорости придонного течения, так и в виде температуры, соответствующей бесконечной конвекции, то есть бесконечной скорости придонного течения. Исследовано влияние полученных коэффициентов теплопередачи на профили температур частично заглубленных подводных трубопроводов различной протяженности. Выявлено, что для рассмотренного подводного трубопровода наибольшее влияние коэффициент теплопередачи оказывает на первых 0–200 км его протяженности, далее температура флюида сравнивается с температурой окружающей среды. Помимо этого, выявлено, что скорость придонного течения слабо влияет на коэффициент теплопередачи, и рекомендуется выполнять два расчета: при нулевой скорости течения для нижней оценки коэффициента теплопередачи и при температурных граничных условиях на всех поверхностях для его верхней оценки. The objects of research are underwater pipelines. The aim of the work is to compare analytical and numerical methods for calculating the heat transfer coefficient between the transported fluid and the external environment. To achieve the set goal, a comparison of heat transfer coefficients obtained both by analytical methods, including those implemented in the PIPESIM software, and by numerical modeling of the heat exchange process in the Ansys Fluent and Ansys Mechanical software was performed, which showed good convergence of the OTC 23033 analytical method with the results of numerical modeling. When solving thermal problems in Ansys Mechanical, two extreme cases are considered: with boundary conditions on the pipe and soil surfaces both in the form of convection corresponding to zero velocity of the bottom current, and in the form of temperature corresponding to infinite convection, that is, infinite velocity of the bottom current. The influence of the obtained heat transfer coefficients on the temperature profiles of partially buried underwater pipelines of different lengths was investigated. It was found that for the considered underwater pipeline, the heat transfer coefficient has the greatest influence in the first 0–200 km of its length, after which the fluid temperature becomes comparable with the ambient temperature. In addition, it was found that the bottom current velocity has little effect on the heat transfer coefficient, and it is recommended to perform two calculations: at zero current velocity for the lower estimation of the heat transfer coefficient and at temperature boundary conditions on all surfaces for its upper estimation.

Regulating ball response to impact is one way to control ball exit velocity in baseball. This is necessary to reduce injuries to defensive players and maintain the balance between offense and defense in the game. This paper presents a model for baseball velocity-dependent behavior. Force-displacement data were obtained using quasi-static compression tests to 50% of ball diameter (n = 70 baseballs). The force-displacement curves for a very stiff baseball (Model B) and a softer type (Model C) were characterized by a Mooney-Rivlin model using implicit finite element analysis (ANSYS software, version 6.1). Agreement between experimental and numerical results was excellent for both Model B (C10 = 0, C01 = 3.7e6 Pa) and Model C (C10 = 0, C01 = 2.6e6 Pa). However, this material model was not available in the ANSYS/LSDYNA explicit dynamic software (version 6.1) used to quantify the transient behavior of the ball. Therefore the modeling process was begun again using a linear viscoelastic material. G∞, the long-term shear modulus of the material, was determined by the same implicit FEA procedure. Explicit FEA was used to quantify the time-dependent response of each ball in terms of instantaneous shear modulus (G0) and a decay term (β). The results were evaluated with respect to published experimental data for the ball coefficient of restitution at five velocities (13.4–40.2 ms–1) and were in agreement with the experimental values. The model forms the basis for future research on baseball response to impact with the bat.

Full textAbstract:
Since centrifugal pumps consume a mammoth amount of energy in various industrial applications, their design and optimization are highly relevant to saving maximum energy and increasing the system’s efficiency. In the current investigation, a centrifugal pump has been designed and optimized. The study has been carried out for the specific application of transportation of slurry at a flow rate of 120 m3/hr to a head of 20 m. For the optimization process, a multi-objective genetic algorithm (MOGA) and response surface methodology (RSM) have been employed. The process is based on the mean line design of the pump. It utilizes six geometric parameters as design variables, i.e., number of vanes, inlet beta shroud, exit beta shroud, hub inlet blade draft, Rake angle, and the impeller’s rotational speed. The objective functions employed are pump power, hydraulic efficiency, volumetric efficiency, and pump efficiency. In this reference, five different software packages, i.e., ANSYS Vista, ANSYS DesignModeler, response surface optimization software, and ANSYS CFX, were coupled to achieve the optimized design of the pump geometry. Characteristic maps were generated using simulations conducted for 45 points. Additionally, erosion rate was predicted using 3-D numerical simulations under various conditions. Finally, the transient behavior of the pump, being the highlight of the study, was evaluated. Results suggest that the maximum fluctuation in the local pressure and stresses on the cases correspond to a phase angle of 0°–30° of the casing that in turn corresponds to the maximum erosion rates in the region.

Aim: This study aims to investigate the impact of von Mises stress distribution on the cervical spine and soft tissue of the neck at different flexion angles of 0°, 15°, 30°, 45°, and 60°. Materials and Methods: Finite element analysis of the neck's cervical spine and soft tissue was performed separately in Ansys Discovery Live software, a possible approach for simulating the mechanical behavior of the neck. Three-dimensional (3D) models were created in 3D Max software and static structural analyses of soft tissues were performed in ANSYS by using the Finite Element Method. The maximum stress distributions of the cervical spine in cervical vertebra bodies at different flexion angles were analyzed at the lowest and highest stress values of 0° and 30°, respectively. For the intervertebral contact surfaces, the lowest and highest stress values were determined at 0° and 45°, respectively. Results: The value of stress showed a linear increase with increasing flexion angles in the soft tissue of the neck. The observation that the stress values obtained at different flexion angles were arbitrarily in either positive or negative directions when compared to the upright posture suggests that the effect of neck flexion on stress distribution in the cervical spine is complex and multifactorial. The change in stress values in the soft tissue of the neck was always positive and linear with increasing flexion angles. Conclusion: People who work with technological devices are prone to a musculoskeletal disorder associated with forward flexion of the neck, and individuals are encouraged to adopt a neck flexion angle between 0° and 15°. This finding could help guide the development of strategies to reduce the risk of neck injury or damage in different postures.

An ANSYS FLUENT commercial software was employed to investigate the flow and thermal characteristic of the flow in the range of Reynolds number 10,000 to 50,000 and nanoparticle volume concentration from 0% to 2%. The results show that by increasing the Reynolds number, the Nusselt number increased for both pure water and nanofluid cases. The thermal conductivity and viscosity of the nanofluid were increased with an increase in the particle volume concentration and yields enhancement of heat transfer.

The paper delineates the procedure to assess probable failure sections through the dynamic conditions of a vertically tapered frame using the experimental modal analysis (EMA), which is validated through the finite element analysis (FEA). The modal parameters are experimentally determined by the frequency response functions (FRFs) using the accelerometer, force transducer, electro-dynamic shaker, dynamic signal analyzer (DSA) and post processed by the ME’Scope software. The ANSYS Workbench 14 was used for finding the modal parameters through the FEA. The FEA model was also tested by convergence study. The boundary conditions of the vertically tapered frame in the FEA is kept similar to the EMA. The values obtained by the two methods have been compared for their proximity.

Abstract This paper presents a strength analysis of a calcaneal nail (material Ti6Al4V and stainless steel) which is used to treat complex heel fractures. The application focuses on a unique calcaneal nail, the C-NAIL, produced by Medin a.s. (Nové Město na Moravě, Czech Republic). The paper first presents an analysis of fracture types, treatment methods and loading of the calcaneus. It then presents an analysis of limit conditions and loading. Calculations (displacement and stress) are performed for 6 and 7 fixing screws using FEM (Ansys Workbench 14 software). The calculation involves a new, original application of an elastic foundation, which effectively replaces the complex interaction of the calcaneal nail and the heel bone.

ABSTRACT Objective: The aim of his study was to evaluate the stress on tooth and alveolar bone caused by orthodontic intrusion forces in a supraerupted upper molar, by using a three-dimensional Finite Element Method (FEM). Methods: A superior maxillary segment was modeled in the software SolidWorks 2010 (SolidWorks Corporation, Waltham, MA, USA) containing: cortical and cancellous bone, supraerupted first molar, periodontal tissue and orthodontic components. A finite element model has simulated intrusion forces of 4N onto a tooth, directed to different mini-screw locations. Three different intrusion mechanics vectors were simulated: anchoring on a buccal mini-implant; anchoring on a palatal mini-implant and the association of both anchorage systems. All analyses were performed considering the minimum principal stress and total deformation. Qualitative analyses exhibited stress distribution by color maps. Quantitative analysis was performed with a specific software for reading and solving numerical equations (ANSYS Workbench 14, Ansys, Canonsburg, Pennsylvania, USA). Results: Intrusion forces applied from both sides (buccal and palatal) resulted in a more homogeneous stress distribution; no high peak of stress was detected and it has allowed a vertical resultant movement. Buccal or palatal single-sided forces resulted in concentrated stress zones with higher values and tooth tipping to respective force side. Conclusion: Unilateral forces promoted higher stress in root apex and higher dental tipping. The bilateral forces promoted better distribution without evidence of dental tipping. Bilateral intrusion technique suggested lower probability of root apex resorption.

Full textAbstract:
Aircrafts with high aspect ratio wings are most eligible candidates for high altitude and long endurance flights. Such wings show a non-linear deformation behavior because of structural geometric non-linearity. In the present study both linear and non-linear static aeroelastic behaviors of a high aspect ratio rectangular flat plate wing are analyzed using a simplified approach. The main emphasis lies in the tremendous change of lift distribution on the flexible high aspect ratio wing when large deflections are incorporated in the static aeroelastic analysis. The computational static aeroelastic simulations are performed in the finite element method based commercial software ANSYS-14. The aerodynamic load is calculated using the strip theory. Since the aero-load changes with the twisting deformation hence a user defined script is written using ANSYS parametric design language (APDL). The computationally achieved divergence velocity results are compared with the analytical results. The results of parametric study at different flight load conditions and angles of attack have highlighted the role of geometric nonlinearities in both bending and twisting deformations. The impact of follower pressure forces on the aeroelastic response is also investigated.

Composite materials have a number of properties that make them attractive for use in aerospace applications. The impact behavior of fiber reinforced composite materials is much more complex than conventional metallic structures due to a number of different failure modes on the inter laminar and intra laminar level. The aim of this study is to investigate the effects of temperature and thermal residual stresses on the impact behavior and damage of glass/epoxy laminated composites. To this end, thermal stress analyses of the laminates with lay-ups [90/0/0/90] s, [90/0/45/45] s, [0/90/45/-45] s, [45/0/-45/90] s are carried out under different temperatures by using ANSYS software. Also, the impact analysis on the laminated composites was performed at the different range of impact energies under different temperatures. The specific energy values and impact parameters were obtained and compared for each type of specimens and temperatures.

Introduction: The worldwide application of digital technology has presented dentistry with transformative opportunities. The concept of digital dentures, incorporating computer-aided design (CAD) and computer-aided manufacturing (CAM) techniques, holds the promise of improved precision, customization, and overall patient satisfaction. However, the shift from traditional dentures to their digital counterparts should not be taken lightly, as the intricate interplay between oral physiology, patient comfort, and long-term durability requires thorough examination. Aim: The aim of the present study was to evaluate and compare the dimensional changes of 3D printed (NextDent, 3D Systems, The Netherlands) and conventional heat-cured (Vertex BasiQ 20, 3D Systems, The Netherlands) denture base resin after immersion in artificial saliva for different periods (7, 14, and 30 days) and then applying 3D simulated deformation, tensional strength, and stress, using the ANSYS software (ANSYS Inc., Pennsylvania, USA). Materials and methods: For the manufacturing of the test specimens, an STL file was created, using the Free CAD Version 0.19 (Free CAD, Stuttgart, Germany). The dimensions of each specimen were 20 mm in width, 20 mm in length, and 3 mm in thickness. Two hundred experimental bodies were created and divided into two groups (n=100), with half fabricated using a 3D printer (NextDent 5100, NextDent, 3D Systems, The Netherlands) and the other half prepared using the traditional method of heat-curing polymerization in metal flasks. The test samples were then weighed using an analytical balance, immersed in artificial saliva for three periods (7, 14, and 30 days), and reweighed after water absorption. After desiccation at 37°C for 24 hours and then at 23±1°C for 1 hour, the samples were weighed again. Then the data were entered into the specialized program ANSYS and the 3D simulation tests for deformation, tension, and stress were performed. Statistical analysis was performed using the IBM SPSS Statistics Version 0.26 statistical software, which includes descriptive statistics and one-way ANOVA analysis. Results: The findings weren’t statistically significant and indicated that the average metrics for the 3D-printed experimental test samples were marginally greater than those recorded for the conventional samples. Conclusions: Within the limitations of this study, it is possible to conclude that 3D-printed resin has a lower capacity to withstand deformation, tension, and stress under simulated conditions than conventional dental resin. However, they do not exceed the values accepted by the ISO standard for clinical application of this type of material.

Research on the microchannel and its flow and heat transfer properties has received much attention. This study employed Autodesk Inventor software to build the model, and the Computational Fluid Dynamics software (Ansys Fluent 14) was used for numerical simulation. Taguchi analysis methods, ANOVA, and Minitab statistics testing were used. The results obtained for single response analysis for temperature, pressure, and velocity values are reasonable. With the optimal model for temperature difference () being W2H1S2 and the temperature difference across the model (), the pressure difference across the model (), maximum velocity in the channel (), and maximum outlet velocity () are W3H1S3, W1H1S3, W3H2S1, and W1H1S2, respectively. The analysis results for multi-response between the two values of velocity and pressure also achieved reasonable results with precisely defined parameters with response optimization for and , and the optimal model achieved is W(0.8mm), H(0.3mm), S(2.91), W(0.4mm), H (0.3mm), S(1.67), respectively.

In an era of compact cooling requirements, where air cooling systems seem to be ineffective and consistently, being replaced by liquid cooled systems, with greater watt density heat energy dissipation. Such cooling systems must work with good quality enabling high efficiency. Hence, an attempt is made to fabricate an aluminum alloy based flat plate heat sink with cover and base plate using friction stir welding. The base plate is machined to obtain channels for fluid flow and the cover plate is fitted in the base plate and welded. Two such configurations of these heat sinks were fabricated with varying channel lengths and number of channels. The flow characteristics of the model for these configurations were analyzed numerically using computational fluid dynamics (CFD) software tool, ANSYS fluent 14.
