Crack tip mesh size - Interface cracks ?

Choose a channel featured in the header of iMechanica: 

Hello everybody,

                   I am working on FE Simulation of interface cracks. To this end, I use modified VCCT, CSDEM and other such methods to determine mesh independent strain energy release rate (G) and Mode mixity (ψ). Now I have a fundamental doubt.

vcct in ANSYS

Hi friends,

I am a new researcher in fracture mechanics of composite area.

i want to find out the fracture toughness using VCCT method in Ansys.

please help me . i dont know how to extract the crack nodal force dcb specimen in Ansys.
