Analyses of contact pressure and stress amplitude effects on fretting fatigue life
Article Abstract:
Elastic-plastic finite element analyses of a cylinder-on-plate configuration, studied experimentally, were performed to provide an explanation for the decrease in fretting fatigue life with increasing contact pressure. The study shows that the decrease in fretting fatigue life with increasing contact pressure can be related to the increase in the local stress range amplification alone, without any regard to interfacial shear stress or slip amplitude.

The modeling of unusual rate sensitivities inside and outside the dynamic stain aging regime
Article Abstract:
A method of modeling negative rate sensitivity and zero rate sensitivity in the context of a state variable model that normally represents positive rate sensitivity is studied. Application of the theory to the behavior of a modified 9Cr-1Mo steel showed excellent qualitative and quantitative modeling of the mechanical responses including the prediction of strain rate changes at positive rate sensitivity and rate insensitivity.
