hi every one
I am trying to model transverse loading on composite material using czm. Verifying my model with:
https://www.sciencedirect.com/science/article/abs/pii/S0266353816301208
my model show excessive compliance with cohesive layers. Theoretically this should happen when the penalty stiffness is too low, but I have tried many other higher penalty stiffness presented in the literature and the results are the same. Can anyone familiar with czm check my model and give me a hint please?
