Hello,
I have faced a similar problem.
I apply displacement boundary condition(displacement 2 and fixed support), and CZM on the contact interface for a three-layered structure. The bonded connection is established between the top and middle layer interface (in red color line), as shown below
The middle layer material is hyperelastic material properties, and the fracture of the bonded interface is defined as CZM, as shown below
After solving, where the detachment occurs, the elements of the middle layer are violated, as shown
May I ask how to solve this kind of problem.
Thank you.
