摘要：

A model is developed herein for predicting the fatigue life of creep-fatigue damage interaction, which is induced by combined high frequency mechanical loading and low frequency temperature variation, i.e. stepped-isothermal fatigue loading. The model is derived from continuum damage mechanics. In the model, the interaction between creep and fatigue damage is considered to be nonlinear. To validate the proposed model, a cast aluminum alloy is fatigue tested at 200-350 degrees C and 350-400 degrees C. The results show that good agreement can be achieved between predicted life and experimental data. (c) 2013 Elsevier Ltd. All rights reserved.
