When the E–N curve Model, or the
Combined Basquin and Coffin Manson Model is evaluated, the computed number of cycles to failure is limited as follows: for low loads, when the number of cycles to failure becomes very large, the
Cycle cutoff parameter,
Ncut, provides an upper bound for the value of
ctf.
When the Coffin–Manson Model is evaluated, the accumulated effective inelastic strain range,
interface.
Dei, is also calculated.
