Dear All,

Curently Im trying to implement the Damage initiation and Damage Evolution in Abaqus LCF with the parameter =Hysteresis Energy.

The Calibration of this model requires 4 constants c1, c2, c3, c4, I have found example constants but cannot find the way in which they are derived, or where they come from for that matter.

Does anyone know what model the Hysteresis Energy damage in Abaqus is based on and how one would find these constants for their material.

Thanks in advance!
