cohesive zone modeling under comprssive loads
I have square plate with circular inclusion, I have added a cohesive elements around the inclusion. Inclusion is harder and matrix is softer. I have applied both tensile and compressive loads on tha plate, I could able see debonding for tensile loading but i could not see debonding fro compressive load. I am using maximum stress criterion for damage initiation and for damage evolution fracture energy. I am doing simulations in Abaqus. Now I want to replace normal stress criterion by some shear criterion, can I able do it. Is there any shear based crietrion for cohesive zone modeling.
With Warm regards
