Not found anyone else who dared to explain with inner details of derivation and establish the science. Thank you Sir

Sir I'm very thankful for your great help.

Mr Professor:
Congratulations for your lecture.
This chapter present quite well the meaning of Gi-ii.
In order to introduce the Gic-iic(critical energies) in abaqus (XFEM - cohesive elements for simulation of a crack propagation ) how i should derive them?My knows are the modulus (in tension compression and shear) and the strengths (in tension compression and shear).Should i have to make the additional experiments in order to get the critical equivalent displacements of a bilinear low (uc) and then to calculate the area and get the Gic-iic?
Thank you very much for your attention and I'm really sorry for the inconvenience I may have caused to you.
