  2. 1. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Author : Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Abstract : 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. READ MORE

  4. 2. Residual Stress Analysis and Fatigue Assessment of Welded Steel Structures

    Author : Zuheir Barsoum; Jack Samuelsson; Dan Zenkert; Stephen Maddox; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; fatigue failure; welding; weld defects; welded joints; stress concentration; residual stress; linear elastic fracture mechanics; welding simulation; finite element analysis; fatigue crack growth.; Engineering mechanics; Teknisk mekanik;

    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. 3. Modeling Residual Stress Fields in Soft Tissues : with Application to Human Arteries

    Author : Tobias Olsson; Linköpings universitet; []
    Keywords : Continuum Mechanics; Modeling; Residual Stress; Soft Tissues; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. READ MORE

  6. 4. Residual Stress Distributions in Additively Manufactured Parts : Effect of Build Orientation

    Author : Prabhat Pant; Ru Lin Peng; Johan Moverare; Kjell Simonsson; Jonathan Almer; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM;

    Abstract : 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.

  7. 5. Soft Tissue Mechanics with Emphasis on Residual Stress Modeling

    Author : Tobias Olsson; Anders Klarbring; Ray W. Ogden; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Mechanics; Residual Stress; Growth; Remodeling; Engineering mechanics; Teknisk mekanik;

    Abstract : 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. READ MORE
