Effect of applied stress on the compressive residual stress introduced by laser peening
Transactions of the JSME (in Japanese), 2016 Peening is the process which is able to be generated compressive residual stress and is known to be effective for preventing SCC initiation and improvement of fatigue strength. Laser peening is used for the nuclear power plant components in order to prevent SCC initiation.
