Abstract

This letter serves to report some fractographic observations and two different threshold values from Mode II fatigue tests conducted on sharply–notched bar specimens of mild steel using an increasing load technique. Thresholds for tensile mode growth and shear mode growth agree well with corresponding results from the literature. The presence or absence of residual stress influences the fatigue crack initiation and growth behaviour.
