Title: 
Fatigue crack growth of Al 7475 T761 under constant and variable amplitude loading
Author(s): 
Institution: 
Universidade Estadual Paulista (UNESP)
Abstract: 
Experimental programs in constant and variable amplitude loading were performed to obtain a x N curves and to study retardation in fatigue crack growth due to overloads. The main aim of this research program was to analyse the effect of overload ratio and number of overload peaks. The effect of underloads, before and after the overload blocks was also studied. The generalised equation of Paris-Erdogan type was used for modelling of obtained data on crack propagation under constant amplitude load.
