When material damage reaches a particular level, it degrades and fails in the finite element of continuum damage mechanics. So, how do you simulate material failure in ABAQUS using node-release?

Hi,

If by node release you mean element deletion, you must first define a damage criterion and damage evolution in the Property module; then, select the STATUS variable from the Field output (see attached figure). If the stress reaches the damage criterion, the element and its nodes will be deleted.

If you need to know more, refer to the following link.

If your model is composite:

I hope these links will help you.

Best wishes.
