  1. 1. Implementation of thermomechanical laser welding simulation : Predicting displacements of fusing A AISI304 T-JOINT

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Anton Rolseth; Anton Gustafsson; [2021]
    Nyckelord :Laser welding; Finite element method; ABAQUS; Thermomechanical simulation; Heat source models; DFLUX; Element activation;

    Sammanfattning : Laser welding is an advanced joining technique with the capability to form deep, narrow, and precise welds. Numerical models are used to simulate the process in attempts of predicting distortions and stresses in the material. This is done to reduce physical testing, optimize processes and enable integrated product- and process development. LÄS MER

  3. 2. Numerical and experimental analysis of adhesively bonded T-joints : Using a bi-material interface and cohesive zone modelling

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Andreas Andersson Lassila; Marcus Folcke; [2018]
    Nyckelord :adhesive; cohesive zone modelling; Finite Element Method; mixed-mode; T-joint; fracture; experiment; cohesive laws; Bi-material Interface;

    Sammanfattning : With increasing climate change the automotive industry is facing increasing demands regarding emissions and environmental impact. To lower emissions and environmental impact the automotive industry strives to increase the efficiency of vehicles by for example reducing the weight. LÄS MER

  4. 3. Numerical simulation of residual stresses in a weld seam : An application of the Finite Element Method

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Maciej Maczugowski; [2017]
    Nyckelord :Finite element method; residual stresses; temperature distribution; fatigue life; weld power; time step; T-joint weld model; Butt weld model.;

    Sammanfattning : Articulated haulers are fundamental equipment to transport material. The load carrying structure on a hauler consists mainly of welded frames. During welding of the frames high residual stress will be introduced. These stresses may have a significant impact on the fatigue life of the frames. LÄS MER

  5. 4. Simulation of laser welding in sandwich rocket nozzle

    Kandidat-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Filip Elfving; [2015]
    Nyckelord :FEM; Sandwich; T-joint; residual deformations; residual stresses; Laser;

    Sammanfattning : This bachelor thesis has been carried out at GKN Aerospace. GKN is a member of European Space Agency, designing and manufacturing rocket-nozzles for the Ariane rockets. The manufacturing process entails many welds. Weld-simulations have been made to investigate stresses and plastic strains on simplified geometries. LÄS MER
