Summary:

Material stress strain relations of cast aluminum are both temperature and strain rate dependent when used for themomechanical fatigue analysis. In the present paper, A unified visco-plasticity relation and several classical plasticity relations available in commercial finite element code ABAQUS are compared in their capability and computation efficiency for high temperature cyclic material stress analysis. The unified viscoplasticity considers simultaneously plasticity and creep offers the best, most accurate approach for a description of the stress and strain behavior. For certain applications, when the needs of a speedy computation weighs more than accuracy, classical plasticity can be used to approximate the viscoplastic behavior. In such situations, it is shown that combined hardening model is most promising in capturing observed phenomena
