  1. 1. 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 : This thesis deals with simulation of mechanical cutting. It focuses on orthogonal cutting. Thus it is possible to use two-dimensional models. The strong thermo-mechanical coupling must be accounted for in the model. READ MORE

  2. 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

  3. 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

  5. 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
