Double Cantilever Beam Debonding problem

LB_01

Hi everyone,

I'm using Optistruct to perform a Double Cantilever Beam adhesive debonding simulation and I'm getting illogical results. As you can see in the picture the adhesive is being stretched a lot and the bigger damage can be seen more towards the fixed end of the beam, which is not how it should be.

Could you help me to fix this behavior? I'm attaching also the .fem model

Thank you so much.

Hello,

I’ve reviewed the model, and the issue appears to stem from the element normal vectors. To resolve this, you should correct the normals to align as shown below:
