Specimens made of this steel were subjected to uniaxial constant-amplitude and random loading with both zero and non-zero mean values of loading. For determination of the steel fatigue life, the energy parameter including the mean value of loading was proposed. Under random loading, cycles were counted with the rain flow algorithm, and fatigue damage was accumulated with the Palmgren-Miner hypothesis. For the registered stress histories, elastic-plastic strains were calculated with the kinematic hardening model proposed by Mróz.}, type={Article}, title={Estimation of fatigue life under uniaxial random loading with zero and non-zero mean value by means of the strain energy density parameter}, URL={http://journals.pan.pl/Content/124919/PDF-MASTER/3_MECHANICAL_53_2006_4_Karolczuk_Estimation.pdf}, keywords={random loading, mean stress, energy models}, }
