The application of Miner's rule using a loading issued from a mock-up of a RHR system (removal heat system) of PWR plant, made of 304 steel gives a very important non-conservative fatigue life in strain control when strain fatigue curve is used. This result is due to the absence of sequence effect in Miner's rule. Many non linear damage accumulation models have been proposed to get a sequence effect...
In this paper, we propose a damage accumulation model for open cell aluminum metal foams subjected to fully reversed cyclic loading based on three different approaches: linear, quadratic and exponential. Toward this aim, an analysis of the fatigue behavior and a failure criterion are necessary. The fatigue behavior will be analyzed using the well known statistical Weibull model, and the failure criteria...
