1. Fatigue Analysis of Welded Structures Using the Finite Element Method
Abstract : Fatigue design and analysis of steel and composite bridges is generally based on the notion of the nominal stress using the classified S-N curves with corresponding fatigue classes for typical details. Such an approach can yield unrealistic the estimation of the load effects for structure components because of an ever increasing number of structural details and loading situations resulting in a limited number of possible treatable design cases.

2. Fatigue evaluation of welded details – using the finite element method
Abstract : The fatigue evaluation of welded details is generally based on the notion of nominal stress, using the classified S-N curves with corresponding fatigue classes for typical details. An approach of this kind should be used with extra caution to ensure that the load effects for components are accurately captured, because an ever-increasing number of welded details are resulting in a limited number of possible treatable design cases.

3. Computational weld mechanics - Increased accuracy in fatigue assessment, distortion and residual stress analysis
Abstract : This thesis work is concerned with the mechanical response of welded steel structures, which are distortions, residual stresses, and fatigue. The accuracy of fatigue assessment, distortion and residual stress analysis using Computational weld mechanics (CWM) is focused. READ MORE

4. Direct Calculation of Wave-Induced Loads and Fatigue Damage of Container Vessels
Abstract : Container ships and their rules for fatigue design are in several ways differentcompared with other types of commercial ships such as tankers and bulk carriers. Forexample, most modern container ships have a pronounced bow flare and an overhangstern. READ MORE

5. Multi-axial fatigue of welded details
Abstract : Welds and welded joints are nowadays very common in steel structures. Since thewelded parts also are susceptible to fatigue, they can have a major influence on thetotal life of the structure. READ MORE
