Crack Propagation by Cohesive Zone Modeling in Abaqus

[RayBowen]

Hi everyone,

I read some articles about Cohesive Zone Modeling (CZM) and Crack Propagation in Abaqus. And I successfully simulated several examples with sandwich structure subject to static loading, where adhesive joints bond two steels together.

I used Damage law for Traction-Separation Laws-->Quads Damage. I skipped the Interaction Module since all the three sections share the interface nodes.

However, I cannot have any crack propagation even under huge displacement. And I did find some similar problems post in different forums, but no solution has been found out.

I appreciate a lot if you can help me.

Thanks,
