... of induction-hardened parts, for shafts and axles the transmission of torque is a major requirement. In a study designed to optimize torsional strength, Ochi and Koyasu evaluated the effect of increasing carbon content on induction-hardened shafts ( Ref 21.16 ). Figure 21.8 , from their study, shows torsional...

... that for parts conventionally heat treated ( Fig. 10.2 ). Induction-hardened axles consist of a hard, high-strength, tough outer case with good torsional strength and a tough, ductile core. Many axles also have a region in which the case depth is kept very shallow so that the part can be readily straightened...

To use the stress/strength distribution concept to analyze fractures, one should be familiar with the six basic loading geometries, including tension, compression, bending, torsion, contact stress, and shear. A review of some of the loading geometries is presented in Ref 1...
