Development of analytical strength estimator for self-piercing rivet joints through observation of finite element simulations

Analytical strength estimators for self-piercing riveted (SPR) metal sheets under the lap-shear and the cross-tension modes are developed. The modeling is based on the local mechanical responses of rivet and sheet metals during the riveting process and joint strength tests, which are investigated using finite element (FE) simulations as virtual experiments. The FE simulations consist of the riveting process model and lap shear test model, and...
