✦ Synopsis

Semi-elliptical surface cracks, growing due to cyclic loading of plates, undergo significant shape change during the propagation process. An equation for predicting this shape variation for any combination of tension and bending loading is presented. These growing cracks change their shapes such that they follow preferred propagation patterns (PPPs). These PPPs are determined herein for any combination of tension and bending loading. Some of the main characteristics of the PPP are determined and discussed. It is shown that for a given cyclic loading field, the PPP represents an upper limit on the aspect ratio of any surface crack growing due to this cyclic loading.

A new statistical theory is proposed for the analysis of fatigue crack propagation, based on the concepts of fracture mechanics and random processes. Focus is centered on conceivably more useful information of the random time at which the crack size grows to any specific value. Given an initial crac
