Prediction of residual stress relaxation of shot peened 2024-T351 aluminum alloy: part 2

The initial compressive residual stresses induced or inherent in a component will not remain stable during the life of the component, it relax and redistributed. In design of the component, it is important to consider the relaxation of residual stress phenomenon. In this study, equations to predict...
