  2. 1. Efficient finite element modelling and simulation of welding

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

    Abstract : This thesis presents development of methods, methodologies and tools for efficient finite element modelling and simulation of welding. A novel 8- to 16-noded solid shell element has been developed. It uses only displacement degrees of freedom, thus it can easily be connected with a regular brick element. READ MORE

  4. 2. Finite element modelling and simulation of welding of aerospace components

    Author : Andreas Lundbäck; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : Fusion welding is one of the most used methods for joining metals. This method has largely been developed by experiments, i.e. trial and error. READ MORE

  5. 3. Simulation-based feedback control of welding processes

    Author : Fredrik Sikström; Bengt Lennartson; Gunnar Bolmsjö; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element modelling; Heat transfer; Model order reduction; Sensors; Weld simulation Controller design; Automatic control; Reglerteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Fusion welding for joining of metals is an important manufacturing process widely used in industry, and very appreciated for its usefulness. This thesis presents a strategy dealing with the problem of designing feedback control for robotised welding. READ MORE

  7. 5. Material modelling for simulation of heat treatment

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

    Abstract : Heat treatment of materials is a fundamental metallurgical process. Materials are subjected to heat treatment to relieve internal stresses, reduce brittleness and to improve machinability. The properties of materials can also be altered such as hardness, strength, toughness, and wear resistance to suit particular applications. READ MORE
