Behaviour of Textured FCC Sheet Metals

Abstract

The simulation of texture evolution and the stress-strain response of FCC sheet metals is considered. A rate-sensitive crystal plasticity model is employed and results are presented for certain textures and deformation paths where closed-form analytical solutions can be obtained for the stress states, slip distributions and lattice spins during in-plane biaxial stretching. Examples where analytical solutions for forming limit diagrams have been obtained are also given. For the above applications, rate-independent behaviour is treated as the limiting case of zero strain-rate sensitivity.
