Adhesive zone of edge between two body

    • Cathy Jiang

      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?
