Fatigue assessment of ship structure
WebAccurate fatigue assessment of ship structures is an important part of the structural reliability. As a result of accumulated fatigue damage, fatigue cracks may occur earlier … Webspot stress approach. For fatigue strength assessment of ships, structural stress approach is found to be a viable alternative as employing the mesh size insensitive charaçteristics. Further study for the fatigue strength assessment of ship and offshore structures are required with different mesh sizes and shapes. COMPARISON OF STRUCTURAL STRESS
