Abstract:

Clamped contacts subjected to vibratory loading undergo cyclic relative tangential motion or micro-slip near the edges of contact. This cyclic micro-slip, known as fretting, leads to removal of material through a mechanism known as fretting wear and formation and growth of cracks through a mechanism known as fretting fatigue. In aircraft, fretting fatigue occurs at the rivet/hole interface leading to multisite damage which is a potential failure mechanism for aging aircraft. A finite element model of a current fretting fatigue experiment aimed at characterizing fretting in riveted joints is detailed. A non-symmetric bulk tension is applied to the specimen in addition to the loads transferred from the fretting pad. The model is verified through comparison to the Mindlin solution for a reduced loading configuration, in which the bulk tension is not applied. Results from the model with the bulk tension show that the distribution of micro-slip in the contact is not symmetric and that for some loads reversed micro-slip occurs. Finite element results are given for the effects that four different sets of loading parameters have on the maximum tensile stress induced by fretting at the trailing edge of contact. It can be shown using multiaxial fatigue theory that this stress controls fretting fatigue crack formation. This maximum tensile stress is compared to that of the Mindlin solution for a symmetric distribution of micro-slip. This stress is also compared to that of a variation based on the Mindlin solution for the cases with a non-symmetric distribution of micro-slip. It is concluded that the solution based on the Mindlin variation and the full finite element solution lead to similar predictions of the maximum tensile stress, even when the shear traction solutions differ significantly.

Abstract:

The analysis of textile composites is complicated by the complex micro-structure. It is not practical to account for this microstructure directly using traditional finite elements. A new type of finite element was developed to efficiently account for microstructure within a single element. These new elements, which are referred to herein as macro elements, performed well in initial tests.

Abstract:

A numerical approach for forming simulation and manufacturing of micro part, based on the elastic and the rigid-plastic finite element methods by using grain element and grain boundary element, is proposed to simulate MEMS/micro-structural deformation behavior of material during micro forming. The idea is to present the polycrystalline material by an aggregate of so-called grain element that describes the plastic deformations of each individual grain in view of micro-structure. This grain element is connected by grain boundary element to account for shear deformation between grains. The main objective in this study is to develop the reliable finite element model and scheme for micro forming simulation with very thin sheet. The reliability for micro forming analysis is described from the comparisons of the micro-structural deformation behavior between the conventional rigid-plastic finite element analysis and the FE analysis of the developed program with very thin sheet material.

Abstract:

Considerable interest has recently been developed in processing bulk materials through the application of severe plastic deformation (SPD). High pressure torsion(HPT) is one of severe plastic deformation methods. By this method, the material grain size can be refined to 20~200nm, which are nanometer level, and the micro-hardness and mechanical properties of materials can be improved. So the nanometer material can be got through this method. In this paper, the results of the rigid-plastic finite element analysis of the plastic deformation behavior of bulk materials during the HPT processing are presented. The torque and strain patterns of the sample as well as the relationship between the slippage time and pressure are also investigated.

Abstract:

In order to realize the application of finite element analysis in structural optimization of micro-arc oxidation electrode, effects of two kinds of electrode mode (one and two cathodes) on thickness and surface morphology of ceramic coatings prepared by micro-arc oxidation on aluminum alloy were researched by experiment. Meanwhile, Ansoft Maxwell finite element software was used to analysis the main influence factor (electric field intensity). We contrasted the analysis conclusion above with the forecast results in experiment. Effect of electric field intensity on thickness and surface morphology of ceramic coatings were explained from micro level, the correctness of the finite element analysis software was verified. The results show that three electrodes mode is better than two electrodes mode, the former can not only make the thickness of ceramic coatings thicker, but also make sure the size and quantity of discharge channel bigger and more, and growth power enough.

Abstract:

Micro machining becomes more and more important with the tendency of miniaturization of components used in various fields from military to civilian applications. The finite element method software Abaqus is used to model the nonlinear thermal force coupled elastic-plastic micro machining processes. Relatively systematic simulation analysis has been introduced based on the model combining the Johnson-Cook failure criteria, element deletion strategy etc. It reveals that the size effect is dominant while the depth of cut reaches the cutting edge radius. The rake angle plays more important roles on the micro machining than that of the cutting speed.

Abstract:

The precision and accuracy of the final geometry in micro-parts is crucial, particularly for high-value-added metallic products. Micro-extrusion is one of the most promising processes for delivering high-precision micro-parts. The curving tendency observed in micro-extrusion parts is a major concern, significantly affecting the final part geometry. The purpose of this paper was to investigate the driving mechanism behind the curvature in micro-extrusion at room temperature. A finite element (FE) simulation was carried out to observe the influential primary factors: (1) grain size, (2) grain boundary, (3) grain orientation, and (4) bearing length of a 6063 aluminum alloy. The Extrusion Curvature Index (ECI) was also established to indicate the level of curvature in micro-extruded parts. The results showed that the grain boundary at the high strain and die opening area was the dominant factor for single-grain conditions. The interactive effects of the grain boundary and grain orientation also affected the curvature under single-grain conditions. If the number of grains across the specimen increased up to 2.7 (poly-grains), the curvature effect was dramatically reduced (the pins were straightened). For all conditions, the curvature in micro-extrusion could be eliminated by extending the bearing length up to the exit diameter length.

Abstract:

In the process of micro-cutting for the precision small parts, one of the main problems is the micro burrs. The finite element software Abaqus was used to simulate the micro-cutting process of aluminum 2024-T3. To create this model, Johnson-Cook (J-C) model was used to establish the material model, and Arbitrary Lagrangian Eulerian (ALE) method was used to separate the chip from work-piece. The contact friction models which was used between chip and tool was the modified Coulomb friction law. The formation process of micro burrs was simulated dynamically, and the effect of different cutting parameters and tool geometry parameters on burrs forming was analyzed. Furthermore, the general law was obtained. The results provide the guidance for optimizing the tool geometry parameters and cutting parameters to reduce the burrs in micro-cutting with the high surface quality.

Abstract:

Due to the rise of biological and MEMS technology in recent years, some micro flow system components have been paid attentions to developed by many investigators. The importance of micro-pumps manufactured is higher than the other part of micro flow system since it is the power source of the entire micro-flow system and responsible for driving working fluid in the microfluidic system. In actual operation, the instability and bad dynamic characteristics of the micro-pump will cause larger fluid flow mobility error, such as transport behavior and response procedures failure, etc., and even damage the microfluidic system. Therefore, to investigate the stability and dynamic characteristics of a micro pump is necessary. The miniature piezoelectric film micro-pump, made by Microjet Technology Co., Ltd., is employed to study in this work. The computer graphics software SolidWorks is used to build the model of the micro pump. Then, The Finite element analysis (FEA), ANSYS Workbench, is also employed to analyze the dynamic characteristics of this micro pump.

Abstract:

Combining the finite element method and the analytical method, a hybrid finite element-analytical approach is established to calculate the nonlinear dynamic responses of a micro-resonator driven by electrostatic combs accurately for the purpose of programmed dynamical simulations and great shortening of workloads. The spatially discretized equations obtained by using the analytical undamped global mode functions to the nonlinear integro-partial differential equations and the ordinary differential equations of the micro-resonator, in which the coefficients are estimated by the discrete global mode shapes from the finite element method, are used to calculate the nonlinear dynamic responses of the micro-resonator. The results are compared with those merely based on the analytical mode functions of the micro-resonator, which shows that they can reach high accuracy when the elements in the micro-resonator are sufficiently small.

Abstract:

During distraction osteogenesis (bone lengthening) one phase is lengthening and a second phase is consolidation (fixed length, bone maturation). In this second phase of fracture healing, the callus consists of several tissue types. The response of callus bone to mechanical loading can determine the progress of treatment. The mechanical strain distribution could provide additional information of fracture healing in the same way as for bone remodeling. The architecture and tissue properties significantly affect the strength of the whole callus bone. This article focuses on imaging and numerical analysis of bone fracture healing based on input information obtained from micro-CT scans. The objective of this study is to focus on how different stiffness threshold values affect the load carrying tissue architecture and how this further influences the strain distributions within the callus. Finite element simulations are employed to investigate this. A rabbit tibia fracture callus was micro-CT scanned 30 days after osteotomy using an isotropic voxel size of 20 μm. Four computational models were created with different pixel threshold values to cover a wide range of callus tissue properties, with the purpose of finding an optimal threshold value. Optimal means here a finite element model which is computationally feasible and still contains the main load carrying tissue.The values of bone volume/total callus volume (BV/TV), bone area/total callus area (BA/TA), trabecular thickness, structure model index (SMI) were quantified to compare the differences between models. All finite element models were axially loaded to investigate the influence of threshold value on the callus reaction and influence of including the soft tissue. The BV/TV and BA/TA values indicate that for a certain threshold level, finite element models are suitable. However, a too high threshold leads to invalid finite element models. The finite element method (FEM) could be useful tool in understanding of fracture healing process.

Abstract:

The draping and buckling of knitted fabric is simulated based on the micro-mechanical constitutive model with full Lagrange finite element method under gravity load. The micro-constitutive model reveals the mechanical properties of fabric more elaborately, especially fabric has its own properties owing to its micro-knitted structure. In the finite element analysis, the knitted fabric sheet is discretized with 8-node shell elements and reduced-integration method is used. The simulated results are in good agreement with the experimental observations. The work provides a theoretical and technical basis for the development of the virtual trial system of garments.

Based on experiments, micro-mechanics and finite element theory, nanocomposite ceramics is simplified as representative volume cell in the paper, and in order to study the interaction of the particles, each cell concludes two nano-ceramic particles. We use ANSYS program to construct the cell model and simulate the stress field. The stress distribution and the material properties are obtained. The results show that the stress is uneven in the cell and the elements near the nano-ceramic particle with high stiffness will damage first. Finely, the stress change and damage evolution route are simulated by using the element birth and death technology. The computational results are accordance with experiments and theories.

Abstract:

A hybrid method based on the combination of the volume integral equation (VIE) method and the boundary integral equation (BIE) method is proposed for the micro-macro solution of elastostatic 2D and 3D multiscale problems in bounded or unbounded solids containing interacting multiple inclusions of essentially different scale. The hybrid micro-macro formulation allows decomposition of the complete problem into two associated subproblems, one residing entirely at the micro-level and the other at the macro-level at each iteration. The efficiency of the standard iterative scheme of the BIE and VIE methods for the singular integral equations involved is enhanced by the use of a modification in the spirit of a subtraction technique as well as by the advantageous choice of the initial analytical approximation for interacting inclusions (micro-level) in an unbounded medium subjected to inhomogeneous loading. The latter is evaluated by the macro-scale BIE technique capable of handling complex finite geometries and mixed boundary conditions. The iteration method proposed converges rapidly in a wide class of problems considered with high matrix-inclusion elastic contrast, with continuously varying anisotropic and nonlinear elastic properties of inclusions, as well as with sizes of interacting inclusions differing by a factor varying in the interval from 1 to 107. The accuracy and efficiency of the method are examined through comparison with results obtained from finite-element analysis and boundary element analysis as well as from analytical solution.

Abstract:

A viscoelastic analysis of the biological cell considering the microcellular material properties is carried out in this work. Three separate regions of the cell: the actin cortex, cytoplasm and nucleus are considered. The outer cortex and cytoplasm are modeled using standard linear viscoelastic model (SLS) and standard neo-Hookean viscoelastic solid, and a linear elastic material model is considered for the nucleus. The effect of the material properties of cytoplasm and actin cortex on the derivable parameters from three major experimental studies of magnetic twisting cytometry (MTC) and atomic force microscopy (AFM) and micropipette aspiration (MPA) are analyzed using the finite element method. The bead center displacement for the MTC, reaction force for AFM, and aspiration length ratio for the MPA are the major quantities derived from the finite element analysis. A number of parametric studies are also conducted and it is observed that SLS and SnHS models predict nearly identical results for the material constants.

In this paper, higher continuity p-version finite element, in particular two-dimensional C2 elements are utilized in studying vibrational characteristics of rectangular Flexural Micro-Plates based on the "gradient elasticity theory". In order to verify the computational procedure, results obtained from the finite element framework are compared to the classical plate theory results and to those of the micro-plate and classical plate investigations that are available in literature. Results indicate that the proposed framework, yields highly accurate results. Moreover, it is concluded that, under certain boundary conditions and length scale effects, the differences in predictions are so gross that the validity of classical theory in predicting micro-plates vibrational characteristics can be ruled out completely.

Abstract:

This study is focused on the influences of micro stretching process, miniaturized of micro square hole-flange to stainless steel (SUS304) material, and different thicknesses (0.2, 0.1, 0.05mm) of plate. By undergoing finite element program analysis of material parameter corrected by scale factor, we can discover the differences of different thicknesses of plate during micro stretching forming process. The finite element method in this paper is combined with the plastic flow rule of Dynaform and LS-DYNA solver, finite element deformed theory, and updated Lagrangian formulation to simulate the process of micro square hole-flange. The point of this research is by simulating and analyzing all datum of micro stretching forming process, relation between punch load and stroke, distribution of thickness, distribution of stress and strain, the maximum diameter of flange’s hole and the maximum height of flange. Design three pairs of micro square hole-flange tool undergoing micro stretching experience through SUS304 plate. Compare the experience to the results of the simulation to test the reliability of this analyzing program. Through finite element analysis and the results of the experience, we can discover that the minimum of the thickness, the biggest stress and major strain centralize areas where blank and punch corner meet.

Abstract:

In this study, the change of the natural frequencies in mouse femurs with osteoporosis was investigated based on a vibration test and a finite element. Three groups of the femurs include the osteoporotic group, the treated group and the normal group. In the vibration test, the natural frequencies were measured by the mobility test. For the finite element analysis, the micro finite element model of the femur was reconstructed using the Micro-CT images and the Voxel mesh generation algorithm. From the results, the averaged natural frequencies in the osteoporotic group were the highest, followed by those in the treated group. The finite element models were validated within 15% errors by comparing the natural frequencies in the finite element analysis with those in the vibration test. The developed Micro-CT system, the Voxel mesh generation algorithm, the presented finite element analysis, and vibration test could be useful for the investigation of the structural change of the bone tissue, and the diagnosis and the treatment in the osteoporosis.

The tensile response of three-dimensional angle-interlock woven composite (3DAWC) under quasi-static loading was investigated in experimental and finite element model (FEM) analysis. The FEM analysis was based on micro-structure at yarn level and connected with commercial FEM software ABAQUS/Explicit (ver. 6.10) to calculate the tensile property under quasi-static loading. The experimental and FEM stress-strain results were compared. Good agreement proved that the FEM method based on micro-structure was reasonable and effective and could be used to design 3-D woven structural composite.

Abstract:

The draping and buckling of woven fabric are simulated with the finite element method based on the micro-mechanical constitutive model and orthotropic constitutive model under gravity load. Compared with the traditional orthotropic mechanical model of the fabric, the micro-mechanical constitutive model characterizes the special properties of woven fabric due to its micro-weaving structures. The woven fabric sheet is discretized with 8-nodes shell elements which are designed for finite deformation and suffice to describe the large rotation of fabric sheet during draping, for the sake of simplicity, the nodes of the fabric sheet on the edges of the desk are assumed to be fixed. Compared with the experimental ones, the simulation results with the micro-mechanical constitutive model are in good agreement with the observations. The work paves the way for developing a virtual clothes trial system.

Abstract:

Recycled general-purpose plastic, polypropylene gained general acceptance because of its excellent properties. At the moment, most of experimental tests of short-natural fibers reinforced polymer composites have been concentrated on macro level, lead to un-matured of fine, micro mechanics research work. In this paper, flexural property of short flax fiber-reinforced polypropylene composites was numerical estimated using a FEM model. It has been observed that initial modulus of the composites increases with the rise in fiber volume fraction, while short fiber orientation distribution has little effect on composites; the stress-strain curves almost have no change.

Abstract:

In this article we consider finite element methods for approximating the solution of partial differential equations on surfaces. We focus on surface finite elements on triangulated surfaces, implicit surface methods using level set descriptions of the surface, unfitted finite element methods and diffuse interface methods. In order to formulate the methods we present the necessary geometric analysis and, in the context of evolving surfaces, the necessary transport formulae. A wide variety of equations and applications are covered. Some ideas of the numerical analysis are presented along with illustrative numerical examples.

Abstract:

A micro-meso-macro finite element approach has been developed for simulating the macro-scale damage coupled deformation in a particulate polymer composite (PPC) based structure under tension. A damage model for the PPC structure was developed to define the debonding damage behavior of the structure. The computational results determined in our previous studies by using finite element meso-cell modeling technique were used as the input parameters of the damage model and definition of the constitutive behavior of PPC. A user-defined subroutine VUMAT describing the damage-coupled constitutive behaviour of PPC for defining the material properties of the finite elements for the structure was then built and incorporated into the ABAQUS finite element code. A case example has been given to demonstrate the proposed approach. The macroscale damage process in the simulated component was found to be reasonable.

Abstract:

In this paper, electro-thermal-mechanical theoretical analysis of micro-hotplate-based micro gas pressure sensor is carried out, which is on basis of the classical heat transfer theory and rarefied gas dynamics. Combined with micro-hotplate (MHP) theory analysis of heat transfer and thermal-mechanical finite element modeling, electro-thermal-mechanical coupled analysis of theoretical models with regard to the MHP-based micro gas pressure sensor is built. Then, through the ANSYS-one of the finite element analysis software-the simulation analysis of MHP went well. The simulation results show that MHP generates a smaller deformation because of adding the thermal conductivity, and MHP provides a more feasible analysis method in the theoretical study of micro hotplate.
