How to define different values of fracture energy for each mode by using the principle of pure mode independent behavior in abaqus. particularly using cohesive surface approach.
I planning to perform sensitivity study by varying fracture energy for each mode case, in order to determine which mode is prevailing the fracture phenomenon in the model. This study will be demonstrated considering pure mode independent behavior using the principle of mode independent behavior but unfortunately, in ABAQUS, there is no option any option to define the different value of fracture particularly while using this mode independent context. Therefore, in such case, is there any option to different values of fracture energy in ABAQUS (mode independent case).
