Fillet weld in fin plate joint
The plate/weld is loaded by normal and shear force and bending moment. Analytical model The fillet weld is the only component examined in the study. The weld model has an elastic-plastic material diagram, and stress peaks are redistributed along the weld length. The relation between the weld length and the bending moment resistance of the joint is shown in Fig. 4.3.3.
