Does anyone know about "Fracture energy" for Carbon fiber reinforced plastic cutting modeling in Hashin Failure criteria?

Hi, I modeled unidirectional CFRP cutting process in ABAQUS using Hashin failure criteria. Unfortunately, many researchers did not report the used fracture energies in their model. I found...
