Prediction of Fatigue Crack Path Based upon Green’s Function Theory

Abstract:

It is known that fatigue crack path has an influence on the fatigue life of the structural components. In this study, a method of predicting the crack path is developed based upon superposition of a stress intensity factor (Green’s function solution) for the crack problem subjecting to a pair of concentrated loads. This method has a benefit to give us a complete closed crack path solution, and it is easy to predict the complex crack path in comparison with a numerical prediction by finite element (FE) analysis.
