fracture energy for hashin damage evolution using Abaqus

hi everyone,

i'm modelling the impact on the composite carbon/epoxy using Abaqus 6.9.

i have the questions:

when i use damage evolution for hashin damage criteria,  i need the values of the fracture energy: longitudinal tensile fracture energy, longitudinal compressive frecture energy, transverse tensile fracture energy, transverse compressive fracture energy. i'm suggested to use the values as 12500, 12500,2500,2500. Are these correct? i dont know how to evaluate these values. Is there any suggestions?

wait for reponse.

regard :d
