  2. 1. Deformations and stresses in welded pipes : numerical and experimental investigation

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

    Abstract : In this dissertation, deformations and stresses in welded pipes have been studied both numerically and experimentally. The aim of this work has been to investigate and verify finite element models for simulation of the fabrications of two types of pipe joints. READ MORE

  4. 2. Modelling and simulation of mechanical cutting

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

    Abstract : The commercial success of a new product is influenced by the time to market. Shorter product lead-times are of importance in a competitive market.This can be achieved only if the product development process can be realised in a relatively small time period. READ MORE

  5. 3. Thermo-mechanical modelling of welding with experimental verification

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

    Abstract : Residual stresses and deformations after welding were studied numerically and experimentally. The numerical simulations were performed using the finite element method. In the calculations a thermoelastoplastic material model was used. READ MORE

  7. 5. Coupled thermal, metallurgical and mechanical models of multipass welding

    Author : Lars Börjesson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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
