Three Dimensional Finite Element

In this study, a three-dimensional finite element formulation for polycrystalline plasticity model based on the homogenization method has been presented. The homogenization method is one of the useful procedures, which can evaluate the homogenized macroscopic material properties with a periodical microstructure, so-called a unit cell. The present study focuses on hexagonal metals such as titanium or magnesium. An assessment of flow stress by the presented method is conducted and it is clarified how the method can reproduce the behavior of hexagonal metal.

In this paper, the simulation of the piercing process is performed by the three-dimensional finite-element method in Dieschers mill. The material properties of steel 33Mn2V are introduced. The simulated results visualize dynamic evolution of temperature, especially inside the workpiece. Its show the distribution of temperature on the internal and external surface of the work-piece is non-uniform. The temperature of the internal surface is far higher than that of the external surface of workpiece.
