Abstract

In this paper, we present techniques for fatigue damage evaluation using spectral methodsand a model taking into account confined elasto-plastic behavior. The model is associatedwith a local fatigue approach, covering the whole endurance domain (low cycle and highcycle fatigue). It uses Neuber’s method and is valid for limited plasticity. To validatethis modeling, we perform a correlation between spectral methods, modified spectralmethods and experimental tests. Results presented here are focused on the uniaxial loadingcase.
