Abstract

<div>This research presents a development of the methodology for numerical simulation of the low cycle fatigue life. The sensitivity of the number of pairs of the kinematic hardening parameters on the hysteresis loop of the low cycle fatigue behaviour of stainless-steel working under cyclic loading was investigated. An experimental and numerical investigation was carried out on AISI316L steel under 0.18 % strain loading at 20 ° C to predict the fatigue failure of the component. It is observed that the cyclic elastoplastic response of the low cycle fatigue loading improves as the set of kinematic hardening parameters increases. The numerical simulation performed gave the results in good agreement with that of the experimental results. It can be concluded that the presented methodology can be employed for the estimation of the fatigue life of the stainless steel under repetitive strain loading.</div>
