Hello,

Is it a good idea to define, for the same two surfaces, two contacts:

• One of type bonded, to be used for a CZM analysis
• One of type Frictional. This one will come to action after the debonding in the CZM area?

Many thanks

By default, when the contact opens up due to debonding, a frictionless contact is assumed between the two surfaces where the debonding is complete. One may define coeff. of friction using a command snippet to change it to a frictional contact.

Thank you for your answer. If I do not ask to much, how such snippet should look?
Kind regards

Another question:
Is it possible to use CZM in an axisymmetric analysis(model)? I did find a paper that states that this is possible (it seems it is an APDL analysis), but when I work in Workbench, the contact to apply CZM is yellow.
Many thanks
