The Influence of Hold Times on Fatigue Crack Growth of Aluminum Alloys.

Abstract

The main emphasis during the present contract year has been in four areas: (1) The influence of underload times on fatigue crack growth retardation, (2) investigation of crack closure, (3) the influence of crack surface roughness on acoustic energy transmission, and (4) the influence environment has on the fatigue fracture surface. These will be discussed separately.
