Does anybody have any experience with modeling crack propagation using MPC in abaqus??
I am using MPC to release nodes along my crackpath (which happens to be along the line of symmetry). I wanted to know as to how the MPC is defined in terms of dependent and independent nodes. I have written a USDFLD for damage criteria, which if becomes =1 then the node is meant to be released. I have also written a MPC subroutine but I am not seeing any node release in spite of Damage=1.
I would be glad if anyone could tell me how the nodes are defined / connected in the subroutine or share their valuable experiences.
