Prediction of residual stress relaxation of shot peened 2024-T351 aluminum alloy: part 1

It is important to account for residual stress relaxation phenomenon in the design of the component. Specimens of 2024-T351 aluminium alloy were used in this study. The specimens were shot peened under three different shot peening intensities. Cyclic tests for two load magnitudes were performed for...
