Understanding a failure occurrence and its propagation will lead to a better appreciation of welded joints from reliability point of view. Fracture mechanics is mechanics of solids containing planes of displacement discontinuities (cracks) with special attention to their growth. In this thesis, the fracture mechanics analysis in ANSYS for welded structure with cracks are investigated by determining the stress intensity factors, deformation and compared for different materials. Theoretical
