The constitutive model adopts a two-parameters heuristic equation, which coefficients are evaluated using an idealization of the S-N diagram rather than the more commonly used Paris law. The approach is implemented in the finite element code ABAQUS and validated with analysis on Double Cantilever Beam specimen.
