Application of a simplified method to evaluate the inelastic state due to fretting fatigue

The simulation of fretting fatigue with the classical incremental method results in the lengthy and repeated calculations. This paper presents a simplified analysis method for the modeling of the mechanical behavior of inelastic state due to fretting fatigue. This approach has been proposed by Zarka et al. in order to predict the nature of the limit state of structures and the structural behavior under cyclic loading. It decreases significantly the computational complexity and duration of the calculations in comparison to classical incremental formulations.This approach is applied to the problem of dry contact between cylider pads agians flat specimen. The calculations results are in good agreement with the experimental observations.
