Fatigue crack can be a controlling factor in the life of some welding components, such as vertical and horizontal stiffener. In this study, The fatigue tests were carried out on the out-of-plane gusset fillet welded joint. In addition, investigations of three-dimensional fatigue crack propagation of gusset welded joint using the finite element analysis of FEMAP with NX NASTRAN and FRANC3D. The 3D crack growth simulations can be performed to compute stress intensity factor(SIF), which are used to determine crack propagation cycles.
