FATIGUE RELIABILITY ANALYSIS OF WELDED JOINT BY USING FRACTURE MECHANICS APPROACH

This thesis presents a fatigue reliability analysis of welded joint by using fracture mechanics approach. Numerically analysis was focused on a transverse-stiffener to bottom flange welded joint of a typical steel bridge. Crack growth model is based on the principles of fracture mechanics theory,...
