    Abstract : In this thesis we develop a generalized finite element method for linear thermoelasticity problems, modeling displacement and temperature in an elastic body. We focus on strongly heterogeneous materials, like composites. READ MORE

  2. 2. Numerical Analysis of Evolution Problems in Multiphysics

    Author : Anna Persson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Regularity; generalized finite element; localized orthogonal decomposition; multiscale finite element method; Thermoelasticity; Riccati equations; thermistor; linear elasticity; Joule heating; parabolic equations; regularity; multiscale; finite element method;

    Abstract : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.

  3. 3. Modelling and Analysis of Cutting Forces, Traction Loads and Thermoelasticity of Carbide Cutting Tools in Turning Operations - Theory and Experiments

    Author : Per-Olof Sturesson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Transfer; Finite Element Method; Metal Cutting; Turning; Material technology; Materiallära; materialteknik;

    Abstract : In modern manufacturing the production safety is often the key factor to achieve good product quality. Factors that influence the production safety are many, durability of machining centres, electric power supply and also the tool life. The tool life is governed by the ability to resist wear and failure. READ MORE

  4. 4. Goal-Oriented Adaptive Finite Element Analysis in Computational Material Mechanics

    Author : Fredrik Larsson; Chalmers University of Technology; []
    Keywords : visco-plasticity; a posteriori error estimation; thermo-elasticity; mesh refinement; adaptivity; FEM; elasticity;

    Abstract : This thesis is concerned with error control in computational material mechanics. A posteriori error estimation and adaptivity for finite element discretizations is investigated. Based on the technique of solving a dual problem, it is possible to control the accuracy of arbitrary quantities. READ MORE
