A finite element model is developed for the
simulation of vibration stress relief (VSR) after welding. For the
nonresonant vibration, the reduction in stress strongly depends on
the amplitude of vibration. For the resonant vibration, the
vibration frequency is the key for stress relief. The vibration
frequency should be close to the structure natural frequency for the
desired vibration mode. Only small vibration amplitude is required,
which will be amplified during vibration. Vibration time does not
have a major impact on vibration stress relief. When the amplitude
of vibration stress relief is large, the treatment will be more
effective.
