1. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies
Sammanfattning : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. LÄS MER
2. Residual Stress Distributions in Additively Manufactured Parts : Effect of Build Orientation
Sammanfattning : Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased.

3. Modeling Residual Stress Fields in Soft Tissues : with Application to Human Arteries
Sammanfattning : Biomechanics or Mechanics of Biology comprises many different fields. This thesis deals with soft tissues or living tissues and the fact that these materials live in a pressurized environment. This means that an unloaded tissue may not be stress free. The stress in an unloaded body is usually called residual stress. LÄS MER
4. Soft Tissue Mechanics with Emphasis on Residual Stress Modeling
Sammanfattning : This thesis concerns residual stress modeling in soft living tissues. The word living means that the tissue interacts with surrounding organs and that it can change its internal properties to optimize its function. LÄS MER
5. Residual Stress Analysis and Fatigue Assessment of Welded Steel Structures
Sammanfattning : 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.
