  1. 16. Development of a Methodology for Efficient FEM Pre-processes to Aid Simulation-driven Design

    University essay from Linköpings universitet/Maskinkonstruktion

    Author : Mattias Bäckman; Josef Kling; [2018]
    Keywords : FEM; Welds; Automation; MDO; HyperMesh; Simulation-driven design; Design Automation; Pre-processes; Mesh;

    Abstract : With both tougher competition and legislations, companies always strive to improve their products while cutting unnecessary costs. This master’s thesis investigates if the after-treatment systems department at the heavy-duty vehicle company Scania CV AB in Södertälje, Sweden can improve their development process by implementing automated FEM pre-processes for welded sheet metal components.

  3. 17. Residual stresses in Ti-6Al-4V from low energy laser repair welding

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Peter Ericson; [2018]
    Keywords : Micro laser welding; Low energy welding; Ti-6Al-4V; Ti64; Residual stress; Response Surface Methodology; Repair welding; Welding simulation; Mikrolasersvetsning; Lågenergetisk svetsning; Lågenergisvets; Ti-6Al-4V; Ti64; Restspänningar; Response Surface Methodology; Reparationssvets; Svetssimulering;

    Abstract : Millimeterstora och svårupptäckta defekter kan uppstå internt i stora och komplexa gjutgods av Ti-6Al-4V, ibland går dessa oupptäckta tills detaljen genomgått mekanisk bearbetning och en stor kostnad redan har gått in i den. Dessa defekter och andra industriella olyckshändelser leder till ett behov av additiva reparationsmetoder där den för tillfället rådande metoden är TIG-svetsning. READ MORE

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

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

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

    Abstract : 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. READ MORE

  5. 19. Estimation of Fatigue Life for Welded Gears Using LEFM

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Richard Tynander; [2017]
    Keywords : ;

    Abstract : The aim of this thesis is to estimate the high cycle fatigue life of welds using finite element methods and liner elastic fracture mechanics (LEFM). Develop a new method of calculating the fatigue life that can replace the old method in use today at GKN Driveline. This is a continuation of an earlier master thesis1. READ MORE

  6. 20. Inductive weld of joints for optical fiber pipe

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Muhammad Usman; [2017]
    Keywords : Parallel resonant circuit; ZVS; Matlab; COMSOL; Mandi; Skin effect; Proximity effect; Modified Wheeler formula; Current-sheet approximation.;

    Abstract : The current study presents an induction heating system design for fiber optics pipes joints. Remote heating methods are probably inconvenient due to non-uniform heat distribution resulting in unreliable joints. READ MORE
