Thank you so much for your comment. My question was for example if i am using the mixed mode fracture, since both normal and tangential stresses exist with a slight dominance of the tangential direction, can we put when defining the CZM parameters in the mixed mode which direction is dominant. Concerning the damping coefficient, I have noticed that when i am changing it from 1e-2 s to 1e-3 s to 1e-4 s, there are alot of changes in the debonding map, then how can i choose the best coefficient?n
