| Abstract: | In this paper, a driving stress finite element method of elastic-plastic large deformation based on implicit time integrating
algorithm and an eight-chain molecular network model is used for the numerical simulation of the simple shear test of polycarbonate
(PC) materials. The simulated results are compared with experimental ones. The strain localization propagation for the shear
band deformation for simple shear deformation is investigated numerically. The effects of microstructure parameters in the
model on strain softening and orientation hardening of the PC are discussed in detail.
