Cavitation Fatigue Strength Jet Peening Residual Stress Surface Modification
Cavitation normally causes severe damage in hydraulic machinery such as pumps and valves. However, cavitation impact can be used for surface enhancement as same way as shot peening. The peening method using cavitation impacts are called “cavitation shotless peening (CSP)” as shots are not required . The great advantage of CSP is that the peened surface is smoother than shot peened one. This is one of reasons why impovement of fatigue strength of metallic materials peened by CSP is better than that of shot ...

Crack Closure Stress Crack Depth Microwave Water Environment
Quantitative evaluation of small cracks in stainless steel under water which was use to simulate the environment of u nclear reactor was demonstrated. The crack depth was evaluated by the means of the microwave dual frequency technique , and the crack closure stress was estimated based on the compliance technique. The cracks were detected significant ly with larger closure stress and the effect of the closure stress to the evaluation of crack depth was investigated....
