Abstract Scope |
A numerical approach integrating the crystal plasticity and phase field model is presented in this study. In the proposed computational modeling, in addition to the local slip activities of polycrystalline metals, the non-crystallographic shear band formation is formulated and implemented in the crystal plasticity finite element method. Then, the local inhomogeneity of microstructure including the shear band formation in the cold rolling process is simulated and its effect on the texture evolution during deformation and heat treatment is analyzed. The texture change in the annealing process is predicted by generalizing the strain energy release maximization model into the phase field model. The calculated rolling, recrystallization textures, and the anisotropic mechanical properties of the metallic sheets are compared with corresponding experiments for the validation of the proposed modeling. |
