Hello Ashish, thank you for your reply!

I don't quite get the idea and could you explain a little bit more? Since the CZM is defined for a bonded contact, after the debonding how can the bonding arise? if so, it would not see any load drop after the debonding since the contact is still there. or the contact is different from a normal one?

like shown in the figure where the circled part indicates debonding has occurred. Is there still a contact in the gap?

Thank you for your professional advice!
