Abstract:
Vibratory stress relief (VSR) is a localized cyclic plasticity phenomenon,and residual stress relief occurs when the vector superposition of induced cyclic stress and residual stress exceeds the local yield stress of the material.Simulations of Vibratory stress relief were processed by a rheological plasticity model,in which the effects of dynamic stress amplitude,dynamic strain amplitude,vibration frequency,vibration cycle and material yield stress on VSR were analyzed......
