Three Dimensional Finite Element

The three-dimensional finite element analysis was performed to determine an optimum die design and the corresponding sheet-blank shape for stamping a part of motorcycle oil tank. To save the computation time, an equivalent drawbead model was adopted to replace the actual drawbead shape in the finite element simulations. The forming limit diagram constructed from stretching tests was also used in conjunction with the finite element results to predict the occurrence of fracture. The optimum die design and the corresponding sheet-blank shape obtained from the finite element analysis was validated by the achievement of defect-free production panels. The advantage of using the finite element analysis for the stamping die design was thereby confirmed.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.

Abstract With the help of the finite element analysis software ANSYS, this paper establishes a finite element model of a fully enclosed sound barrier of elevated road, calculating and analyzing the stress of supporting structure under different working conditions, checking the strength, stiffness and stability of the structure under the most unfavorable working condition. Finally we optimize the structure according to its characteristics.

In this paper, the four-point shear (FPS) specimen is studied for different combinations of crack depth (a/W) and specimen thickness (t/W) to width ratios. Extensive 3D finite element analysis (FEA) has been carried out, and comprehensive solutions of fracture parameters produced. From the results of the finite element analysis, the size of the plastic zone is studied at various points through-thickness. Through these analyses, the effects of considering finite-thickness specimens are illustrated.

The purpose of this paper is to investigate the stress concentration and fatigue of the prosthetic blood vessels. A three-dimensional finite element analysis was performed with three loading. The good man fatigue thoery was introduced for the fatigue study. As the results, the stress concentration and fatigue mode can be determined. The results prove that the mechanical property of the prosthetic blood vessels can be smiulated through the finite element analysis.

In the present work, the finite element analysis was employed to study the distribution and level of thermal residual stress generated in matrix reinforced with SO2 nanoparticles. Using Cohesive Element as the bonding of the interface between fiber and matrix, three–dimensional finite element models of periodic cells were established. The results of the models with and without nanoparticles were compared. The residual thermal stressdue to the mismatch of the thermal expansion coefficients between matrix and fibers, especially theshear stress in the interface, decreased with nanoparticles, which could explain the reinforcing mechanism of nanoparticles. Our numerical study can be of great significance in designing new composites with high performance
