This paper presents and validates a model of fatigue crack propagation in resistance spot welded joints; this model is called the “Structural Stress Model” (SSM). Important features of the SSM are that it is based on the physical evidence of fatigue in spot welded joints and on well-accepted descriptors of fatigue more generally. Furthermore, it is usable by designers evaluating fatigue response of structures containing multiple welds. Underlying assumptions of the SSM are also reviewed.
