VSR(vibratory stress relief) principle

VSR(vibratory stress relief) principle
From the micro level analysis, VSR can be regarded as a kind of cyclic loading is applied in the form of an additional stress on parts. When the workpiece is subjected to vibration applied to the alternating stress on parts and components in the residual stress superposition. When the result of superposition of the stressreaches a certain value, the worst part of the stress concentration will exceed the yield limit of the materialis plastically deformed. This is where the residual plastic deformation reduces the stress peaks and strengthen the metal matrix, and then the vibration but also in other parts of the stress concentration is generated on themore serious the same effect until the vibration superposition of additional stress and residual stress of thealgebraic and not cause any part of the plastic deformation, at which time, and both vibration to eliminate residual stress and strengthening of metal on the end of the process.
