  1. 1. 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.

  3. 3. 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

  4. 4. Adhesion and Residual Stress Characterization of HVOF Sprayed Inconel 718 Coatings

    Author : Christophe Lyphout; Chalmers University of Technology; []
    Keywords : HVOF; Residual Stress; Inconel 718; Thermal spray; Adhesion Strength; Finite Element Method; High Velocity Oxy-Fuel;

    Abstract : Thermal spray technology in general is nowadays recognized as an industrial process, mature enough to apply coatings on different substrate materials that protect parts against wear, corrosion, heat, or combinations of these. The quality demands on coating homogeneity and adhesion strength are, nowhere more than in the automotive and aeronautic industries, continuously increasing. READ MORE
