Fatigue Crack Growth under Variable Amplitude Loadings: A Theoretical Study

Abstract:

Article Preview

The purpose of this study was making evident the overload effect in a spectre with constant amplitude cycles. The crack growth simulation was made on cracked specimen and was studied for four loading cases. Fatigue crack growth rate was calculated applying NASGRO equation and the crack growth retardation analyzed.
