I want to visualize my results of the XFEM crack growth in form of a diagram with the time increments or the crack length on the horizontal axis and the Griffith' energy release rate G or the stress intensity factor K on the vertical axis. I am using the energy-based damage model.
I don't know, where to activate those values in the Output History. The best solution for me is, if the energy release rate G can be transformed into the stress intensity factor.
