Title: Verification of the approach to predicting fatigue life of notched specimens of magnesium alloys based on types AM50 and AE42
Keywords: fatigue, fatigue life prediction, hysteresis energy, notches, Mg-alloys

Abstract: Experimental and analytical analyses were carried out to prove the accuracy of the approach for predicting fatigue life of notched specimens made from magnesium alloys. An experimental verification has been performed on specimens for two types of magnesium alloys – AM50 and AE42 subjected to cyclic tension/compression. The approach is based on cyclic plastic strain energy density and effective stress concentration factor and takes into account the dynamics of the fatigue process, including the number of cycles to failure and total hysteresis energy. The effective stress concentration factor Kf that plays a very important role in assessing the fatigue strength of structures is determined analytically. The results based on the energy of dissipation approach demonstrate good correlation with the experimental data for the investigated type of Mg-alloys. fatigue, fatigue life prediction, hysteresis energy, notches, Mg-alloys
