说明： 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.
