Summary:

The extent to which the stress history of a component is non-proportional and out-of-phase can strongly influence the accuracy of the fatigue-life prediction. Phenomenological multiaxial fatigue models are more or less accurate depending upon the extent to which the stress or strain history is non-proportional and out-of-phase. Herein, scalar measures are introduced for characterizing the non-proportional and out-of-phase extent of any stress or strain history. These scalar measures are used to characterize the stress history of a an overhead-cam cylinder-head when subjected to severe cyclic operating thermal loads
