In order to predict the plastic instability and the failure of polymer subsequent to the ductile large deformation, a macroscopic non-coaxial visco-plastic constitutive equation for polymers was derived, as well as a damage evolution equation expressing the generation and annihilation of craze was proposed in the previous report. In this report, the above system is coded into an explicit finite element method considering an inertial effect that is not considered for a numerical example in the previous report despite of including high strain rate dependence. Consequently, it is evaluated that this system is able to predict large deformation and failure of polymer under the impact deformation condition more realistically than the above previous static simulation.
