  1. 1. Fatigue Assessment of Cast Components : Influence of Cast Defects

    Author : Anders Björkblad; Jack Samuelsson; Gary Marquis; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cast nodular iron; fatigue; design rules; fracture mechanics; Vehicle engineering; Farkostteknik;

    Abstract :  This thesis is on the fatigue assessment of cast components with special attention to defects. The primary material in view is nodular cast iron, but also cast steel is considered. However, the fatigue behaviour is in principle valid for general use on other cast metals. READ MORE

  2. 2. Influences of temperature, fatigue and mixed mode loading on the cohesive properties of adhesive layers

    Author : Tomas Walander; Christian Berggreen; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; mixed mode; temperature; multi-axial fatigue; finite element analysis; fatigue; cohesive law; adhesive layer; fracture energy; potential model; Mechanics of Materials; Materialmekanik;

    Abstract : This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. READ MORE

  3. 3. Residual Stress Analysis and Fatigue of Welded Structures

    Author : Zuheir Barsoum; Jack Samuelsson; Jan Langkjear Hansen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; welding; fatigue; finite element analysis; fracture mechanics; residual stresses; Engineering mechanics; Teknisk mekanik;

    Abstract : This licentiate thesis is generally concerned with the fatigue 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.

  5. 5. Fatigue Analysis of Welded Structures Using the Finite Element Method

    Author : Mustafa Aygül; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot spot stress; effective notch stress; the finite element method; orthotropic bridge deck; welded details;

    Abstract : Fatigue design and analysis of steel and composite bridges is generally based on the notion of the nominal stress using the classified S-N curves with corresponding fatigue classes for typical details. Such an approach can yield unrealistic the estimation of the load effects for structure components because of an ever increasing number of structural details and loading situations resulting in a limited number of possible treatable design cases.
