To improve the material characteristics of singleand poly-crystals of pure copper, the respective relationships between crystallographic orientations and microstructures, and the bending and mechanical properties were examined. And texture distribution is also analyzed. A grain refinement procedure was performed to obtain a grained structure. Furthermore, some analytical results related to crys...

This paper presents a new fixture design methodology for sheet metal assembly processes. It focuses on the impact of fixture position on the dimensional quality of sheet metal parts after assembly by considering the effect of part variation, tooling variation and assembly springback. An optimization algorithm combines finite element analysis and nonlinear programming methods to determine the op...

Abstract Today, the hardening Yoshida-Uemori model is implemented in most used FEA stamping codes (Autoform®, Pamstamp®, LS-Dyna®…) with occasionally some variations. This forming material card requested regularly by car manufacturers. The a combined coupled elastic evolution modulus which depends on equivalent plastic strain. According to experimental tests conducted and their identification p...
