Fatigue Assessment of Spot Welds by Approximated Local Stress Parameters
Source abstract
Abstract
Critical annotations are made to the approximate stress intensity factors and notch stresses proposed by S. Zhang (1997) for the assessment of fatigue strength of spot welds. These comments are based on principal considerations and more detailed derivations referring to the publication above.
