Implementation of the Almen Intensity for the Characterization of Laser Shock Peening
Optics & Laser Technology, 2023 One of the key requirements for surface treatment processes in practical applications, is the ability to reproduce the same treatment using the same parameters. This is one of the problems often encountered in laser shock peening (LSP), because there is no direct method of control deployed, without the need for time consuming residual stress ...
