Modeling and Analysis of a Blade/Receptacle Pair for the Prediction of Thermal Cycling and Temperature Dependent Vibration Driven Fretting Corrosion

Two of the major drivers for fretting corrosion are vibration and thermal cycling, with most previous studies focusing on experimental evaluation. It would be useful to develop and test a strategy for using computer modeling techniques to simulate the effects of vibration and thermal cycling induced fretting corrosion. Toward this end, finite element models are developed for a single blade/receptacle pair. Both thermal cycling induced and vibration induced fretting effects are considered. Example studies were performed and the results presented and discussed in detail.
