说明: Jaumann_Umat 和 Grenn_naghdi率用于abaqus二次开发的Vumat用户子程序(Analysis of Grenn_naghdi Rate Display)
These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to verify and apply the Puck Failure Criteria using the commercially available finite element package ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented with different post failure degradation schemes EWM/CSE.
