報告內容簡(jiǎn)介：

Surface mechanical strengthening (SMS) is the most useful process to change the residual stress (RS) distribution, superficial morphology, surface microstructure and surface hardness. The purposes of SMS are to increasing the fatigue life, to prevent the stress corrosion cracking and to increase the wear resistance of mechanical components.

The different SMS methods, such as machining, rolling, shot-peening, will presented. The principal of RS generation by SMS will be synthesis. The application cases of shot-peening will be presented.

Recent development of SMS, such as dual peening, stress peening, ultrasonic peening, water peening (cavitation peening) and laser peening, will be introduced.
