Abstract
This work evaluates the stress intensity factors (SIFs) and fatigue crack growth (FCG) of a corner crack in a prismatic bar under combined cyclic torsion-tension loads. The SIFs at the initial condition and the FCG for different loading ratios of tension stress to torsional stress are presented. For a given tension loading, the larger Mode III SIFs and the shorter fatigue life were found at the model with the crack aspect ratio a/c â  1 and having a larger torsional loading.
