Damage Evolution: ABAQUS Fracture Energy Parameters
I'm using a damage evolution model in XFEM in order to model crack growth, however I am trying to identify the correct Mode I fracture energy for my problem. In particular there seems to be an issue with the units of fracture energy in ABAQUS.
I am using Damage for Traction Separation Laws, Maxps; Damage Evolution Type = Energy; Mixed bode behaviour = Power Law with power value 1; Now at the bottom what should be the input values of Normal Mode Fracture Energy, Shear Mode Fracture Energy 1st direction and Shear Mode Fracture Energy 2nd Direction.
