Variable-amplitude fat@ue studies of 2024-13 ab&num alloy were performed to examine the effect of sheet thickness on fatigue crack growth rate retardation. Results indicated tbat the amouot of retardation increased with decreasing specimen thickness. This phenomenon was attrii to enhanced plastic st

Crack opening loads and the displacements near the crack tip have been measured by stereoimaging for large (through) cracks and small (surface) cracks. These results have been published. The present paper combines these observations and considers them in a new way, showing the relationship between s
## Abstract Results are presented from a recent study of the influence of tensile overloads on fatigue crack growth in polycarbonate. Fatigue cracks were grown under conditions of constant range in stress intensity factor in fourβpoint bend specimens. The data presented here indicate that tensile o
Fatigue-crack propagation data have been obtained for a variety of aluminum alloys. tempers, and products in relatively thick sections of interest for large aircraft shapes. For the higher stress-intensity ranges. the alloys rate in about the same order with regard to resistance to fatigue crack pro
