You can use "CINT" command in Ansys and then evaluate energy release rate using VCCT.

Linan Qiao

It is too in ABAQUS. VCC can be easily self programmed. A comparable technics is the "energy release method", see: C. Marotzke, L Qiao, "Interfacial Crack Propagation Arising in Single-fiber Pull-out Tests", Composites Science and Technonogy 57 (1997) 887-897
