  1. 6. 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

  3. 7. Effect of material grade on fatigue strength and residual stresses in high strength steel welds

    University essay from KTH/Lättkonstruktioner

    Author : Wasim Asgher; [2012]
    Keywords : Fatigue Strength; Fillet Welded Joints; Effective Notch Method; Residual Stress Simulation.;

    Abstract : This thesis work is concerned with effect of material grade on fatigue strength of welded joints. Fatigue strength evaluation of welded joints in as welded and post weld treated condition was carried out with effective notch method. Results of peak stress method have also been compared with those of effective notch method for as welded joints. READ MORE

  4. 8. Investigation of Mechanical Properties of Thermoplastics with Implementations of LS-DYNA Material Models.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Peter Appelsved; [2012]
    Keywords : Glass-fiber reinforced thermoplastics; polyamide; Hill’s plasticity criterion; strain recovery; cyclic loading; cyclic softening; compression strength; 3 point bend test; LS-DYNA;

    Abstract : The increased use of thermoplastics in load carrying components, especially in the automotive industry, drives the needs for a better understanding of its complex mechanical properties. In this thesis work for a master degree in solid mechanics, the mechanical properties of a PA 6/66 resin with and without reinforcement of glass fibers experimentally been investigated. READ MORE

  5. 9. ABAQUS Simulation of Residual Stress Induced by Waterjet Peening

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Yuting Qiao; Junyi Xu; [2012]
    Keywords : waterjet; peening; FEM; ABAQUS; elastic-plastic; numerical simulation;

    Abstract : In this thesis work, numerical simulation model of waterjet peening processing without abrasive particles has been developed to predict the effect of peening process. Two kinds of simulation are used through: one is quasi-static model and the other is transient dynamic model. The results are described by the residual stress after peening. READ MORE

  6. 10. Simulating Residual Stress in Machining; from Post Process Measurement to Pre-Process Predictions

    University essay from KTH/Industriell produktion

    Author : Joanne Proudian; [2012]
    Keywords : ;

    Abstract : Metal cutting is a widely used manufacturing technique in the industry and has been the focus of many research and studies in both academic and industrial fields. Prediction of induced residual stresses in a machined component is essential in a component’s fatigue life and surface integrity approximation. READ MORE
