Abstract:

This study with constant shear friction uses DEFORM 2D software to perform FEM simulation of backward extrusion, and compares to SUPERFORM FEM simulation to realize the variations of forming conditions with the punch force and the final cup height. Effects of frictional factor, punch nose face angle, punch nose radius, and punch seizing length on equivalent stress, equivalent strain, velocity field, punch force, and deformed shape can be explored. Meanwhile using both FEM softwares to simulate can realize variations of both models in order to provide the reference of backward extrusion.

Abstract:

Das Drehmoment bildet sich beim Gewindebohren über die Anschnittlänge und ist eines der wichtigsten Kriterien, um die Leistungsfähigkeit von Werkzeugen zu bestimmen. Mit üblicher Zerspanungssoftware nimmt die dreidimensionale FEM (Finite-Elemente-Methode)-Simulation wegen der hohen Werkzeugkomplexität mit einer Vielzahl an Schneiden sowie unterschiedlichen Eingriffssituationen oft viel Zeit in Anspruch. Der Fachbeitrag stellt die FEM-basierte Software „ToolSimulation“ für die Gewindebohrsimulation mit Drehmomentvorhersage vor. Die Rechenzeit ist bei dieser Software rund 99 % schneller gegenüber anderen 3D-Simulationsprogrammen. &nbsp; In the tapping process, the torque is generated along the tool‘s chamfer length and is one of the most important criteria for evaluating the tapping tool performance. With conventional machining software, the three-dimensional FEM (Finite Element Method) simulation leads to large computing times, due to the high tool complexity with many different cutting edges, as well as different engagement situations. This paper presents the FEM-based software system “ToolSimulation“, which offers a novel way to create and calculate tapping simulations and an implemented torque prediction method. The computing time for a tapping simulation using this software is about 99 % faster compared to other conventional 3D simulation software.

Abstract:

Abstract This article uses finite element software ANSYS/LS-DYNA to analyze the numerical simulation method of projectile oblique penetration into concrete targets. FEM method is commonly used for numerical simulation of projectile penetration into concrete targets, but there is a problem of large deformation of concrete when penetrating concrete targets obliquely, and FEM method is prone to mesh distortion. Based on the experimental results of oblique penetration of the projectile into concrete, this article uses FEM, SPH, and FEM-SPH numerical simulation methods to obtain the numerical simulation results of oblique penetration into concrete targets at different velocities and incident angles of the projectile. The results from the deflection angle of the projectile and the depth of the crater indicate that compared with using FEM and SPH methods separately, FEM-SPH method has higher consistency with experimental results in simulating the oblique penetration of the projectile into concrete.

Abstract:

This work illustrates the analysis of Film Bulk Acoustic Resonators (FBAR) using 3D Finite Element (FEM) simulations with the software OnScale in order to predict and improve resonator performance and quality before manufacturing. This kind of analysis minimizes manufacturing cycles by reducing design time with 3D simulations running on High-Performance Computing (HPC) cloud services. It also enables the identification of manufacturing effects on device performance. The simulation results are compared and validated with a manufactured FBAR device, previously reported, to further highlight the usefulness and advantages of the 3D simulations-based design process. In the 3D simulation results, some analysis challenges, like boundary condition definitions, mesh tuning, loss source tracing, and device quality estimations, were studied. Hence, it is possible to highlight that modern FEM solvers, like OnScale enable unprecedented FBAR analysis and design optimization.

Design/methodology/approach A three-dimensional model was developed simulating the drilling procedure while experimental data, concerning the chip geometry and force components, were used to validate the model. The developed simulation will allow systematically insight on the tools wear progression induced by the developed temperature and stress fields. Two different cases of simulation were examined. A typical simulation was investigated, which erected with all the standard features found in the FEM simulation software. In the second case, all the experimental data were introduced. Findings The simulation results revealed that the advanced developed FEM model describes sufficiently the real chip geometry. Moreover, the FEM calculations provide an effective tool for predicting occurring temperatures, strain and stresses and thus for approaching the real loads of the cutting tool during drilling.

Abstract:

Abstract This paper presents a comparison of two contact pressure calculation methods between two real rough surfaces: a calculation based on FEM (Finite Element Method) using commercial software tool ANSYS and a calculation based on FDM (Finite Difference Method) using analytical functions implemented in programing tool MATLAB. This comparison, lately, leads to the selection of the most appropriate analytical contact model useful for time-effective and precise contact pressure determination. Surface data for numerical simulations are obtained by optical profilometry. For the case of the modelling process of 3D FEM models of rough surfaces the description of their building is included in this article. Furthermore, this paper discusses all challenges connected with the convergence of such simulations and essential post-processing of FEM simulation results, together with their comparison, along the results obtained by user-written MATLAB functions.

Abstract:

Purpose. The main goal of this paper is to develop the numerical model of viscoelastic material using finite element method (FEM). The model was applied to asphalt-aggregate mixtures. Additionally the obtained numerical results with use of different FEM software were compared with experimental data. Methodology. In order to perform the investigation, the numerical specimen was built within FEM software. Material of the specimen was assumed to be viscoelastic. Viscoelastic materials are characterized by a combination of elastic behavior, which stores energy during deformation, and viscous behavior, which dissipates energy during deformation. It was assumed that the behavior of the material corresponds to generalized Maxwell model. The model consists of a spring element in parallel with a number of spring and dashpot Maxwell elements. Generalized Maxwell model consisting of 5 elements was offered at . Mechanical properties of the material correspond to the properties of real asphaltic material. Findings. As the result of calculations the stress and strain state of the asphalt specimen were obtained. To compare mechanical characteristics of the model with experimental data the dynamic elastic modulus and phase angle values were calculated. Originality. Viscoelastic material model based on generalized Maxwell scheme was developed using ANSYS software. In order to compare the numerical model of the material with real asphalt-aggregate mix data, the values of dynamic modulus and phase angle were selected. Analyzing the results of calculations one can see good correspondence of numerical material model to experimental data. Moreover, the numerical data obtained with ANSYS and LS-DYNA software were compared. Practical value. It should be emphasized that FEM gives the possibility of determining stresses and strains for asphalt pavement non-elastic models what is of great importance using mechanistic design procedures.

Abstract:

Water-lubricated rubber bearings are one of the most appropriate bearings for underwater use. Because of the configuration and special application environment, numerical simulation is difficult with FEM software and relevant report is rare. The water lubrication is especially interesting in terms of cost and convenience. As a result of capital cost of water-lubricated rubber bearing and time consuming experiment, the numerical approach with FEM prevails. But owning to the petty gap where lubrication fluid is bounded in, the modeling is very difficult. Three dimensional free modal and stress distribution of the bearing are analyzed in numerical simulating with FEM software. The present work of analyzing model is further worthwhile as the model can give yield results according to experiments. The modal and harmonic analyzing results can be used directly in material design and also the improvement of structure.

Abstract:

Abstract: Finite Element Analysis or FEA is the simulation of a physical phenomenon using a numerical mathematic technique referred to as the Finite Element Method or FEM. This process is at the core of mechanical engineering, as well as a variety of other disciplines. It also is one of the key principles used in the development of simulation software. Engineers can use these FEM to reduce the number of physical prototypes and run virtual experiments to optimize their designs. Finite Element Analysis is used in various fields like structural, fluid flow, heat transfer to estimate the behavior of a component in real environment. There now exists growing body of knowledge connected with the development of mathematical models and numerical simulations of physical model. There are various software packages like Ansys, OptiStruct, COMSOL, Solidworks and many more which provide a close estimate in simulation models. Apart from these software MATLAB also has a Partial Differential Equation (PDE) toolbox which enables us to perform these simulations using some built-in functions and codes. However, a computational numerical technique is not an end of design rather it just provides a great estimate of the final component for which the results are only as good as the input provided and the final component in most of the cases require a physical testing in environment which it is meant to perform as a validation. Keywords: Brake pedal, MATLAB, Partial differential equation (PDE) toolbox, Tetrahedral mesh.

Abstract. For efficiently performing the numerical simulation of electromagnetic continues casting (EMCC) with finite element method (FEM) and finite volume method (FVM) combined scheme, a program integrates with data-format conversion and post-processing was proposed. The conversion of data format realized by linear interpolating, and the post processor developed on a Visual Fortran 6.6A platform using Fortran-95 language and the QuickWin module. Both 2-D and 3-D EM-FEM data calculated by a general-purpose FEM software, ANSYS, could be converted into FVM-data format using this program, and all FVM-data whether scalar quantities or vector ones could be displayed in the manners of cabinet drawing and normal axonometric drawing, which promises the correctness for data format conversion process of FEM/FVM-joint and the convenient analysis of transport phenomena during EMCC numerical simulation. The results of transport simulations and data format conversions indicate that the format-conversion method as well as the post processing is effective and convenient in numerical simulation with FEM/FVM-joint under various EM fields.

Abstract:

The finite element simulation of T-tube hydroforming process is conducted with the FEM software Pam-Stamp 2G 2005. The results of numerical simulation and experiment are compared and analyzed. The tube hydroforming simulations under various internal pressures of constant pressure load path are also conducted. The simulation and experimental results of T-tube hydroforming are compared. The results show that the tube wall thickness distribution is more uniform and the hydroforming effect is more ideal in T-tube hydroforming process with constant pressure load path. The constant pressure load path of T-tube hydroforming is relatively easy to implement in the practical production process. Of the four constant pressure load paths of T-tube hydroforming, the simulation result under constant pressure 150MPa is most ideal.

Abstract:

The subject of the paper is a study of the material behaviour during hot rolling. The process considered is a rolling of round bar in roughing mill group which consist of four passes. The computer simulation of the process shows that the local plastic deformations which appear in the material are extremely large. This fact can leads to extension of surface defects. The dependences of maximum local plastic deformation on geometrical parameters of the calibres have been obtained and analysed during this study. The investigations performed, led to the development of new roll pass design which almost halved the maximum value of local plastic deformation in the material during the rolling. Since full 3D FEM models needs significant amount of computer memory and CPU time, it was not suitable for the performed study which involves a bulk of simulations with different initial conditions. Therefore, the quick algorithms for simulation of rolling processes which based on so-called “2.5D” method have been used. This method, due to number of simplifications, is significant faster then conventional 3D FEM, and at the same time it allows to reach good accuracy of the model. The developed computer software SPLEN(Rolling) which implements “2.5D” FEM simulations was applied for computations and analysis of the results. This software is able to predict the shape evolution of rolled material, as well as distributions of strain, strain rate and temperature within the volume of deformation zone. It has been shown that computer simulation based on “2.5D” FEM with SPLEN(Rolling) software can by efficiently used for optimization of technological procedures in rolling industry.

Abstract:

With the progressive promotion of BIM technology in collaborative design and engineering data management, there are large amounts of project information available for intelligent construction, engineering computation and design optimization. In the construction of subway station, BIM technology is still not mature and the engineering design is generally separate from the engineering safety evaluation. Thus, this paper proposed a technology that integrates BIM and numerical simulation (BIM-FEM/FDM integrated technology) to solve the problem of separation between engineering design and computation. A three-dimensional parametric modeling of subway station excavation was first carried out using the Revit® modeling software. Afterward, a FEM/FDM-process oriented data conversion interface was developed to extract and process the critical information from the parametric BIM model for numerical simulation. Then, under the impetus of an auto-simulation interface, the safety evaluation of subway station excavation was realized automatically and visualized graphically. The research of the BIM-FEM/FDM integrated technology presented in this paper has established a supporting platform to achieve the integration of BIM-based design and safety evaluation for subway station excavation.

Abstract:

Abstract: In this study, the dynamic stability of soil slopes was analysed using the finite element method (FEM). The analysis was performed using the Plaxis 2D software, which is a popular FEM software package. The study aimed to investigate the behaviour of soil slopes under dynamic loading conditions and to evaluate the accuracy and effectiveness of the FEM approach for predicting slope stability. A 2D slope model was created using Plaxis 2D, and dynamic analyses were performed under different loading conditions. A Shake Table was used for simulating the loading conditions at different frequencies and amplitude. The results of the analysis showed that the slope stability was highly dependent on the dynamic loading conditions and the soil properties. Under earthquake like ground motions which were simulated with the help of shake table under controlled environment, the slope experienced significant deformations and displacements. The deformations were calculated in the form of crest settlement and toe settlement. The study also evaluated the accuracy of the FEM approach by comparing the simulation results with the experimental data. The comparison showed that the FEM approach provided a good prediction of the slope behaviour under dynamic loading conditions and could be used as a reliable tool for analysing slope stability. Overall, the study demonstrated the effectiveness of the FEM approach for analysing the dynamic stability of soil slopes and highlighted the importance of considering dynamic loading conditions in slope stability analysis. The study also provided insights into the behaviour of soil slopes under different loading conditions and could be useful for designing safer and more stable slopes in practice.

Abstract:

Many defects relative to stress occur during the complicate casting process, such as hot tearing, residual stress concentration and distortion. Modeling of casting thermal stress during casting solidification process is of great significance to predict and analyze casting stress defects. Involving too many complex influencing factors, the stress simulation is very difficult and retains a hot spot of macro simulation in foundry engineering. Currently most researchers adopt integrated FDM/FEM method, i.e. using finite difference method (FDM) to calculate solidification and heat transferring, while finite element method (FEM) to simulate stress. Some universal commercial FEA packages are usually adopted. This study has tried two kinds of approaches to simulate casting thermal stress. One is based on ANSYS, a well-known powerful FEA analysis software. Another is to develop an independent own copyrighted casting stress simulation system based on FDM. The routes of these two methods were given respectively. To calibrate the simulation system, a stress frame sample and a real practical casting were simulated and pouring experiment was also carried on. The results of simulation were in agreement with the experiment results and practical cases. It indicates that these two approaches can all meet demands. When adopting FDM method, thermal analysis and stress analysis can use the same FD model, which can avoid the nodes matching between different models and reduce the errors of thermal load transferring. It makes the simulation of fluid-flow field, temperature field and stress field unify into one model. This system takes full advantages of mature FDM technology and can be used to simulate the forming of residual stress and predict the occurrence of hot tearing.

Abstract:

The limit drawing ratios of the steel sheets are studied by the numerical simulation using the finite element software PAM-STAMP 2G. The limit drawing ratios of the steel sheets are also measured by the practical Swift cup test. The results of the experiments and the simulations are compared and analyzed. The results show that the overall shapes of the deep drawing parts of the experiment and the simulation are roughly the same. The maximum deviation of limit drawing ratio values between the experimental results and the simulations for two steel sheets with various thicknesses is only 2.2%. The deviation of limit drawing ratio of steel sheet obtained through PAM-STAMP FEM software is small. The PAM-STAMP software is highly reliable for the steel sheet deep drawing simulation.

Abstract:

Extrusion of magnesium billets is associated with large deformations, high strain rates and high temperatures, which results in computationally challenging problems in process simulation. A simulation was carried out using the finite element software ABAQUS. The computed model was rotational symmetric and built up by meshing. Computed parameters including material characteristics and process conditions (billet temperature. reduction ratio, and ram speed) were taken into consideration. The distributions of temperature were different comparing the transient-state extrusion with the steady-state extrusion. The extrusion simulation was the reliable predictions of strain rate, effective strains, effective stresses and metal flow velocity in an AZ31 billet during direct extrusion.

Abstract:

AbstractBauphysikalische Simulationen haben sich im Planungsalltag der Hygrothermik bereits fest etabliert. Die Simulation realer physikalischer Effekte in der Bauakustik, speziell im Leichtbau, und die Möglichkeit, präzise Vorhersagen zu treffen, stellt bisher aber noch eine Herausforderung dar. Mit zunehmender Nachfrage im Holzbau wachsen die Ansprüche sowie der Bedarf an Planungssicherheit. Die zuverlässige frequenzabhängige Prognose des Schalldämmmaßes von Leichtbauteilen könnte ressourcenintensive Messungen einsparen. Bisher hat sich die Finite Elemente Methode (FEM) als geeignete Methode erwiesen, um bauakustische Parameterstudien an Leichtbauteilen durchzuführen und konstruktive Veränderungen in Relation zueinander zu bewerten. In diesem Artikel wird die Simulation einer Holzrahmenwand in Fenstergröße mithilfe der FEM präsentiert. Die Simulationsergebnisse, durchgeführt mit der Software „COMSOL Multiphysics 6.1“, werden mit bauakustischen Messungen verglichen. Das Schalldämmmaß wird mit einer maximalen Abweichung von 5 dB pro Terzband prognostiziert. Bei der FEM ist die Qualität der Eingangsdaten entscheidend, wobei durch Modalanalysen relevante Steifigkeitswerte und Verlustfaktoren ermittelt werden. Dieser Ansatz gewinnt insbesondere bei mehrschichtigen Bauteilen mit anisotropen Materialien an Relevanz. Zusätzlich zur Modellvalidierung wurden anhand des Modells unterschiedliche Parametervariationen durchgeführt, deren Ergebnisse ebenfalls detailliert dargelegt werden.

Abstract:

Sheet metal forming is an important technology in manufacturing, especially in the automotive industry. Today, engineering simulation tools based on the finite elements method are employed regularly in the design of stamping dies for sheet metal parts. However, a bad material model choice or the use of nonaccurate enough parameters can lead to imprecise simulation results. This work uses ANSYS LS-DYNA software to analyze several material models and the influence of their parameter values in FEM simulation results. The main tool to solve these problems is an application designed to assist die stamp designers. The program allows a procedure to be defined to obtain the values of the properties of an unknown material, which combines finite element simulations with real experimental results. Results obtained for the simulation of a real automotive part are analyzed and compared with the real experimental results. Parameters involved in each material model have been identified, and their influence in final results has been quantified. This is very useful to fit material properties in other simulations. This paper fulfils an identified need in the manufacturing industry. In fact, the proposed application is currently being used by a manufacturer of automotive components.

Abstract:

In the present work, the operation of a 6-pulse three-phase rectifier supplying a powerful DC consumer is simulated using the finite element method (FEM). The purpose of the simulations is to research the generation of harmonics from the rectifier circuit and to investigate their influence on the transformer supplying the three-phase bridge rectifier. For this purpose, two co-simulations were made. The first of them is realized with the help of the professional Finite Element Analysis (FEA) software - Ansys Electromagnetic Suite. The voltage-driven model of the rectifier transformer for FEA was built and was used in the Ansys Twin Builder software simulation. The resulting current harmonics from the FFT analysis of the current waves with their amplitudes and phases are input into the primary and secondary windings of the transformer current-driven model in the second electromagnetic-thermal co-simulation in Ansys Workbench to calculate the losses in the transformer. These losses are used in the thermal model to account for transformer heating from higher harmonics.

Abstract:

Abstract The advancement of computational modeling techniques, such as FEM, has allowed to simulate complex machining processes with improved accuracy. Wear prediction is a crucial aspect in understanding and optimizing machining processes, as it directly impacts tool life, surface quality and overall machining efficiency. This work focuses on the FEM simulation, specially utilizing the DEFORM software, in conjunction with the Usui wear model, for wear prediction in machining operations. The Usui wear model, a well-established and widely used wear prediction approach, accounts for multiple wear mechanisms that include adhesion, abrasion, and diffusion. By incorporating the Usui wear model into the FEM simulation framework within the DEFORM software, it is possible to understand wear phenomena in machining processes. The integration of Usui wear model algorithms into DEFORM enables the simulation to accurately predict wear rates, distribution patterns, and progression of tool deterioration. This predictive capability facilitates the identification of critical wear zones and guides proactive measures to improve tool life, reduce production costs, and optimize machining productivity. This work presents research focused on wear prediction in cutting processes, utilizing FEM simulation with DEFORM software and incorporating the Usui wear model. Through a comprehensive analysis of wear phenomena, this research aims to optimize cutting parameters, improve tool life, and contribute to the advancement of machining and manufacturing technologies.

The objective of this paper is to present simulation results of the Thickness Shear Mode (TSM) resonator based on quartz using finite element simulation method. 3D model of quartz resonator and simulations were completed using finite element method in CoventorWare software suite for design and simulation of MEMS devices. Different techniques for simulation of adsorption effect on selective layer were studied: influence of change in mass of the sensitive layer and influence of change in density of the sensitive layer. Analyses of resonant modes were performed for both cases and displacement profiles in selected modes were determined for the resonator under study. Impedance and phase characteristics were calculated and measured for clean sample and sample with selective layer coated. The adsorption model calculates the frequency shift in basic resonant frequency with adsorbed amount of sensed gas.

Abstract:

In recent years, the applications of finite element method (FEM) in metal cutting operations have proved to be effective in studying the cutting process and chip formation. In particular, the simulation results can be used for both researchers and machine tool makers to optimize the cutting process and designing new tools. Many researches were done on two-dimensional simulation of cutting process because the three-dimensional versions of FEM software required more computational time. The present work aims to simulate three-dimensional orthogonal cutting operations using FEM software of Deform-3D. Orthogonal cutting finite element model simulations were conducted to study the effect of cutting speed on effective-stress, strain and temperature in turning process. AISI 1045 was used as work material and cutting tool was TNMA 332 (uncoated carbide tool, SCEA = 0; BR = -5; SR = -5 and radius angle 60o). The emphasis on the designed geometries are limited to the changes in the cutting speed between 100 m/min and 450 m/min. The machining parameters of feed rate and depth of cut were kept constant at 0.35 mm/rev and 0.3 mm respectively. The simulation results show that by increasing the cutting speed causes a decrease in cutting force and effective-strain. On the other hand, increasing in cutting speed will increase effective-strain and temperature of the chip formed.

Abstract:

Modern approaches in simulations of sheet metal stamping processes are based on definition the friction coefficient as not constant, but the different value in different regions, considering the nature of the actual deformation process in each individual region. In this contribution the regression and analytical models to determine the friction coefficients under blankholder and on the die drawing edge by strip drawing test are presented. These models were verified by experimental strip drawing test under the same contact conditions. Zn coated steel sheets for the automotive industry were used in experiments and simulations – extra deep drawing quality DX54D and high strength steel TRIP. The results indicate, that friction coefficients are not constant and depend on the pressure on the die contact surfaces. Friction coefficients were determined also at the cup test by the regression model of drawing versus blankholding force. Conformity of friction coefficients obtained by the cup and the strip tests was confirmed. Model of friction applied in FEM simulation was verified by cup test and good conformity was found out.
