Abstract

Understanding the correlation between materials microstructure and mechanical deformation properties is of importance to sheet forming industry. Multiscale modeling of material behavior is therefore introduced to link the microstructural features to macroscopic continuum materials properties. In this study, crystal plasticity modeling on single grain and polycrystal levels is conducted. The nanoidentiation test on a single grain of a steel sheet is used to calibrate the materials parameters of the single crystal plasticity model with the assistant of the load-depth curve and the comparisons of surface topologies of the pile-ups. With the calibrated parameters, the macroscopic description of the mechanical behavior is predicted by incorporating a full-field homogenization scheme based on the finite element treatment of representative volume elements.
