Abstract
A multiaxial spot weld damage parameter and a basic load-life approach are applied to proportional shear and peel loading for a standard SAE variable amplitude loading history. Miner's rule and the rainflow cycle counting method are used to calculate fatigue damage using constant amplitude load-life test data for various ratios of the combined loading. The calculations are compared to test results for an HSLA galv-annealed sheet steel obtained by using the DaimlerChrysler Spot Weld Design Committee multiaxial spot weld test fixture. The applicability of the methods are discussed, as are the crack initiation and propagation behavior of the specimens.
