The Fatigue of Weldments Subjected to Complex Loadings
Cruciform and double-strap lap weldments were fatigue tested under constant amplitude axial load and SAE Bracket Spectrum load conditions. For the cruciform weldments, fatigue cracks generally initiate at the root but may initiated the toe if higher bending stresses are induced by joint distortion. For double strap lap weldments, the stress ratio (R) and weld shape are the major factors influencing the fatigue crack initiation site.
