Observations of Cracking Behavior in Tension and Torsion Low Cycle Fatigue

Source

A series of tension and torsion low-cycle fatigue tests were conducted on several engineering materials. Detailed observations of nucleation and early crack growth were made. Cracking behavior is shown to depend upon loading mode (tension or torsion), strain amplitude, and material type.

Multiaxial models developed for shear sensitive materials did not correlate multiaxial test results of a tension sensitive material. Differences in cracking behavior for different materials and loading conditions need to be considered in successful life predictions for components subjected to multiaxial fatigue.
