The crack propagation velocity in corroGon fatigue (du/dN), were measured on the Ni-Cr-Mo steel quenched and tempered at 473 or 773 K. The steel with high sensitivity to delayed failure reveals the largest (du/dN), under square load and the smaller (da/dN), under positive saw tooth load. The frequen
In support of Douglas Aircraft Co. structural damage tolerance analysis, crack propagation rates were measured in humid air from lo-\* to 10m3 mm/cycle of several high strength martensitic steels at stress ratios of R = 0.1 and R = 0.5. Increasing the stress ratio was found to decrease the threshold
From previous investigations of the mechanisms of both fracture and fatigue crack propagation, the static fracture model proposed by Lal and Weiss may be thought as reasonable for describing fatigue crack propagation in metals at both low and interm~iate stress intensity factor ranges AK. Recent pro
