Hello guys,

I am working on thesis about a thermal expansion simulation for a 5 layers body, each layer has its own geometry which can be numbered from 1 to 5, started from top.

I am using static structural in Workbench and CZM for contact debonding between 3 & 4 interface.

• The CZM material has a reliable resource.
• Contact type is Bonded
• Both pure penalty and Augmented Lagrange Formulation has been tried.
• Serval Meshing size has been tried whatever is small or big

The expected results in 5x is shown below in first picture, which has a adhesion between the edge during the debonding.

Picture below is my result which didn't show any adhesion of the edge during the expansion.

Any recommandation to solve this problem? I believe is the error brings by boundary consition setting but I couldn't find it.

Hi Cathy,

Can you try sharing the topology?
