A compact although approximate approach to the determination of stress intensity factors (SIFs) for cracked gears based on the use of the weight function method and the complex potentials method of gear tooth stress analysis is presented. A computer code implementing these ingredients in a scheme for stress intensity factor (SIF) determination is described and its accuracy established by comparison with recent results from the literature. The effects of various parameters on SIFs such as number of teeth, type of loading, and direction of crack propagation are presented.
