... and the clearance well. The models, such as elastic-perfect model, linear strain-hardening model, and power strain-hardening model, are the special cases of the present model. The parameters needed in the present model are determined by curve fitting of the actual tensile stress-strain data of tube and tubesheet...

.../underload ratio is introduced. Since most variable amplitude models are based on a constant amplitude model, efforts were also expended to identify a constant amplitude fatigue crack growth model that would be easy to use, requiring the calibration of few (if any) empirical curve-fitting parameters...
