I developed a code to analyze fatigue crack growth using XFEM sigularity method and I issued paris model for crack criterion in FCGR.
my question is:
paris model is used to model the linear region of crack growth (II region). while in this application program calculates crack growth length vs dk from th begining of crack initiotion until end.
is this a correct approach to do so?
I appreciate your valuable comments and replies in advance.
