Elastic-plastic finite element polycrystal model
A finite element polycrystal model is formulated with the initial strain method where the stiffness matrix in FEM is based on the elastic modulus. For the determination of time-independent slips, a new numerical scheme, ``successive integration method'', is proposed, which uses only Schmid's law. The numerical results for a simple tension of nonhardening FCC metal is compared with other theories. Crystal lattice rotations are presented for some examples of loading. A numerical experiment is done to show the evolution of anisotropic due to plastic deformation.
