Abstract
Spot weld failures of complicated structures, such as automotive bodies, are difficult to explain using current multiaxial spot weld failure theory. After introducing the in-plane rotational failure mode, some unexplainable spot weld failures become explainable. The purpose of this report is to introduce the spot weld rotational test, its relative strengths and its response characteristics. It is found that the strength of a spot weld under the in-plane rotational mode is far below the strengths of the same spot weld under other failure modes such as in-plane tensile/shear. The work conducted in this study could be a foundation for a new generation of multiaxial spot weld failure theory development.
