1. Computational weld mechanics : Towards simplified and cost effective FE simulations
Abstract : It is the demand of the world’s ever increasing energy crisis to reduce fuel consumption wherever possible. One way of meeting this demand is by reducing the weight of a structure by replacing thick plates of low strength steel with thin plates of high strength steel in the structure. READ MORE

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. Residual Stress Analysis and Fatigue Assessment of Welded Steel Structures
Abstract : This doctoral thesis is concerned with fatigue life of welded structures. Several topics related to fatigue of welded structures are treated such as; weld defects and their influence on fatigue performance of welded structures, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, welding simulation, residual stress prediction and measurement and their influence on fatigue life.

5. Fatigue Strength of Friction Stir Welded Joints in Aluminium
Abstract : Solid state Friction stir welding (FSW) is of major interest in the welding of aluminium since it improves the joint properties. Many applications where Al-alloys are used are subject to varying load conditions, making fatigue failure a critical issue. READ MORE
