Determining mode-I cohesive parameters for nugget fracture in ultrasonic spot welds

Abstract

Ultrasonic spot welds have been used as a model system to investigate how to determine the mode-I cohesive parameters associated with interfacial fracture of a spot weld. Numerical analyses indicated that, while multiple combinations of the two cohesive parameters (characteristic strength, σ̂ , and toughness, I ) could result in virtually indistinguishable… (More)
