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 stress
reaches a certain value, the worst part of the stress concentration will exceed the yield limit of the material
is 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 the
more serious the same effect until the vibration superposition of additional stress and residual stress of the
algebraic 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.
