Description
Summary:In this study, experimental data is obtained and CPFEM analysis is performed to characterize the constitutive response of f.c.c. crystalline materials. Dislocation density based crystal plasticity model have been used to elucidate the deformation mechanism of the crystalline materials with limited number of grains. The simple shear experiment of multi crystal aluminum is analyzed for the first time. The results from initial orientation which affects the deformation of materials is predicted and analyzed. This research is expected to be a fundamental research about plastic deformation and anisotropy of materials.
