Effect of laser shock peening on residual stress of 316L stainless steel laser metal deposition part

Journal of Materials Research and Technology
In order to improve the residual stress of laser metal deposition (LMD) parts and ensure that the components are in a state of compressive or zero residual stress, laser shock peening (LSP) is applied to the surface of the parts.

Determining Residual Stress in Copper by Nanoindentation in Compressive and Tensile Stress States

Metals
In this study, nanoindentation was employed to determine residual stresses in copper after compression and tension deformations with different deformation levels. Rectangular and cylindrical compression specimens were prepared in order to produce residual stresses parallel or perpendicular to the stress direction.
