Prediction of 7075 aluminum alloy fatigue life by energy method

Abstract

The purpose of this study is to predict fatigue life of 7075-T6 aluminum alloy by an energy-based fatigue model according to interactive Garud multi-surface plasticity model in non-proportional loading and to present their algorithms and code results. Subsequently by using the results of the model, the fatigue life is predicted and compared to experimental data reported in the literature.
