6. Improved Quality Assurance of Fatigue Loaded Structures - The Necessary Shift from Technology Focus towards Information Driven Weld Evaluation
Sammanfattning : The research has shown that the insufficient use of process information leads to unnecessary and costly safety margins in each step of production. This is, in short term, affecting the productivity of the company. Even more serious is the effect that insufficient use of process information has on product and process development in the long term. LÄS MER
7. Computational weld mechanics - Increased accuracy in fatigue assessment, distortion and residual stress analysis
Sammanfattning : 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. LÄS MER

10. Welding of Heavy Structures Subjected to Fatigue
Sammanfattning : Welding is a key process for heavy steel structures, but it is also a weak link of the structure since fatigue fractures in welds are a common cause for failures. This thesis proposes several changes in order to improve the fatigue properties in a cost effective way. LÄS MER
