Study on Path Precdiction of Fatigue Crack Propagating in Stress Field Disturbed by a hole

Abstract

In this study, fundamental theory to predict fatigue crack path propagating in disturbed stress field was proposed. In order to show the validity of the theory proposed here, the basic problem of the interaction between a circular hole and crack tip was discussed. As a result, it was shown that the predicted crack path was almost coincided with the crack path obtained by FEM.
