โœฆ Synopsis

A mathematical model of fatigue crack propagation based on the crack closure concept is proposed. It allows prediction of fatigue crack growth under complex loading sequences on the basis of data obtained under constant amplitude and simple High-Low, Low-High loading sequences. The model explains the influence of single and multiple positive overloads and the interaction of positive and negative overloads. An algorithm for cycle-by-cycle calculation of crack growth is proposed.

The results of fatigue crack growth tests under a block loading consisting of four mean levels are analyzed in terms of equivalent constant amplitude loading concepts. The different models used to determine the equivalent loadings are based on the root mean square (RMS) method, a modified method bas
