| Abstract: | The stamping and spring back process of a sheet metal structure are simulated by no linear CAE software Abaqus. The residual stress and thickness are mapped to CAE model. The effect of material thickness thinning and residual stress on the vibration characteristics of engine hood is considered and the analysis precision can be increased. |

| Keywords: | residual stress stamping mapping mode Abaqus |
