Title: An energy-based approach for predicting fatigue life of magnesium alloys
Keywords: fatigue, fatigue life prediction, hysteresis energy, Mg-alloys

Abstract: A modified energy-based approach for predicting fatigue life of magnesium alloys is described. The approach is based on cyclic plastic strain energy density and takes into account the dynamics of the fatigue process, including the number of cycles to failure and total hysteresis energy. The modified coefficients in the proposed approach have been obtained from experimental tests under symmetrical loading. An experimental verification has been performed on smooth specimens for magnesium alloys AZ91, AM50 and AE42 subjected to cyclic tension/compression. A predictive capability of the approach is found to be with good agreement to the experimental results for the three types of Mg-alloys.
