Abstract
In this chapter, the fracture behavior of an S355 electron beam welded joint is simulated with the Rousselier, Gurson-Tvergaard-Needleman (GTN), and cohesive zone models separately. First, each model is discussed and the method identifying the model parameters is given. Second, the simulation results on the crack propagation of compact tension (C(T)) specimens with the initial crack located at different weld regions are given. Finally, the cohesive zone model is compared with the other two models, showing its superiority.
