Abstract
From the study of the crack propagation data in fatigue, a parameter in the form P = m log δK + C has been suggested, where the slope m and the intercept C are functions of the variables like stress ratio R, frequency w, and temperature T. Case studies where data are available for various stress ratios have been made and a Master Curve connecting the crack propagation rate da/dN and the parameter P has been obtained. Experimental data for various values of δK and R have been found to agree well with the theoretical prediction. © 1979.
