  1. 11. Coupled thermal, metallurgical and mechanical models of multipass welding

    Author : Lars Börjesson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : This thesis deals with modelling and simulation of thermo mechanical processes in multipass welding. The aim of the simulations is to predict the residual stresses and/or the deformations that occur after welding. These residual stresses and deformations are caused by the high temperature gradients due to the local heating. READ MORE

  2. 12. Simulation methodologies within virtual manufacturing applied on mechanical cutting

    Author : Peter Åström; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Virtual manufacturing, that is, simulation of welding, heat treatment, cutting and other manufacturing processes is becoming more and more used as a tool for prediction of material- and mechanical properties in modern industry. By simulations we refer in this case to FE-simulations of the thermo-mechanical effect of the manufacturing process on the component in question. READ MORE

  3. 13. Electrochemical machining: towards 3D simulation and application on SS316

    Author : A. A. Gomez-Gallegos; UK University of Edinburgh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical machining; 3D Simulation; FEM; stainless Steel 316; surface Finish; Maskinteknik; Mechanical Engineering;

    Abstract : Electrochemical machining (ECM) is a non-conventional manufacturing process, which uses electrochemical dissolution to shape any conductive metal regardless of its mechanical properties and without leaving behind residual stresses or tool wear. Therefore, ECM can be an alternative for machining difficult-to-cut materials, complex geometries, and materials with improved characteristics, such as strength, heat-resistance or corrosion-resistance.
