Abstract

The ultimate strength of resistance spot welded joints fabricated from a wide range of steel grades, weld button size, and sheet thickness are reported for lap-shear and cross-tension specimens subjected to quasi-static and impact loading conditions. Test data are analyzed with respect to energy, impact speed, and loading rate. Loading rate is identified as a critical, test system independent parameter to reflect the strain rate sensitivity of the steels. An equation is fitted to the ultimate strength test data as a function of loading rate which is proposed to predict the separation of spot welded joint under dynamic loading. The model is validated by test data from open literature generated from other type of specimens and/or dynamic test conditions.
