Experimental and numerical investigations of crack propagation on S355NL steel electron beam welded joints are presented. Mechanical properties are obtained from tensile test results of flat specimens extracted from the base material (BM), the fusion zone (FZ) and heat affected zone (HAZ), respectively. Based on metallographic investigations, numerical calibration of Rousselier parameters are performed on notched round specimens. The same parameters are used to predict the ductile fracture of compact tension (C(T)) specimens with initial crack located at different regions. Numerical results are compared with the experiments in terms of force vs. Crack Opening Displacement (COD) as well as fracture resistance (JR) curves
