  1. ; ; ; (, International Journal of Fatigue)
    A hybrid structural stress method is presented for significantly simplifying spot weld representations in fatigue evaluation of complex spot-welded structures while retaining a high degree of accuracy in structural stress computation. The method is formulated by extracting nodal forces and moments around a group of domain elements connected to a spot weld represented by a regular beam element. Through a systematic decomposition technique, existing closed-form solutions, previously only valid for modeling single-spot weld test specimens, can now be used for calculating the relevant structural stresses under complex loading conditions in structures, as validated its ability in correlating fatigue test data.
