Analysis of Micro/mesoscale Sheet Stamping Processes Based on Crystalline Plasticity Model

Abstract

A Taylor-type crystalline plasticity model, implemented into the commercial finite element analysis software, is coded as a subroutine to investigate the behavior of a stainless steel sheet with a body centered cubic (BCC) structure in the current study. Thickness variations of the sheet are examined under the micro-groove formation procedures. Effects of the spatial distribution of crystallographic orientations on the thickness distribution over the sheet are also demonstrated. Numerical results, based on the sheet with textured orientations, are in good agreement with the associated experimental measurements reported in the literature.
