I know it is not possible from reading the manual, but just in case I am ignorant.
basically I would need to create some state variable according to equiv plastic strain (from prager-druger plasticity model), and use it to enable damage. In Abaqus/Standard it is easy, use user defined field variable. However, such thing does not exist in Explicit. It seems to me that in explicit, the only way to create some user define field/state variable is through vumat. but that would mean I need to write the entire constitutive model from scratch while abaqus already has a perfectly good one that has been written much better than I would do it myself.
is there anyway that I walk around it?
