Vibration stress relief (VSR) is a technique used to achieve post manufacturing stress relief as well as dimensional stabilisation of castings, forgings and fabrications. The VSR process relieves residual stresses in components by vibrating the component at its resonant frequency. read more
Residual stresses are those stresses that are locked into the component as a result of the manufacturing processes. Residual stresses therefore form the datum on which the applied loading stresses need to be superimposed. As is often the case, a highly detrimental situation may result if these stresses are additive.read more
