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.
