摘要：

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 result 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 anisotropy due to plastic deformation. The numerical code of the present model is quite simple and can be applied to arbitrary loading paths.
