Hi agambhir_be20

How many allowed substeps are defined?  Is this being run as a large deformation analysis?  Have you double checked the CZM properties?  You may want to run a simple two element (like two cubes meshed each with just one element) test to make sure the debonding is defined as you expected.  A simple typo could result in the debonding being too strong...I've made that mistake plenty of times to know!
