  1. 1. Micro-architectured materials for noise and vibration control in high voltage products – design and modelling

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Alec Chamberlain; [2021]
    Keywords : Microarchitectured; lattice; elasticity; viscoelasticity; computational; homogenization;

    Abstract : Many Hitachi ABB Power Grids (HAPG) products vibrate and emit noise, but legal limitations of these parameters fuel the development of energy absorption methods used on products. Methods such as Constrained Layer Damping (CLD). READ MORE

  3. 2. The influence of modelling variables in FEM evaluation of fillet welded structures

    University essay from

    Author : Marko Cordasic; [2020]
    Keywords : ;

    Abstract : Valmet is a world leading company in the pulp-, paper- and energy industry and is a manufacturer of e.g. paper machines. These paper machines are largely composed of steel frames for which beams and plates are often joined by welding. READ MORE

  4. 3. Infuence of the modelling of truss joints made of hollow tube sections in finite element models

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mattheüs Lucassen; [2019]
    Keywords : Truss joints; Circular Hollow Sections CHS ; Fatigue; Finite Element Modelling FEM ; Crane; Boom section; Local joint exibility LJF ; Stress concentration factors SCF ; Fackverksled; Cirkulära ihåliga proler; Utmattning; Finita Elementmetoden FEM ; Kran; Kranarmsektion; Lokal ledexibilitet; Spänningskoncentrationsfaktorer.;

    Abstract : Several boom segments form the crane boom. These segments are often truss structures formed out of circular hollow sections, which are welded together forming the truss joints. A adequate modelling of these truss joints is very important for operational strength and life. READ MORE

  5. 4. A digital image correlation method for detection of fatigue cracks in non-load carrying T-joints

    University essay from KTH/Lättkonstruktioner

    Author : Björn Jonsson; [2018]
    Keywords : ;

    Abstract : In dynamical loaded welded structures fatigue life is often a limiting factor. Common practise is to reduce nominal stress by increased material thickness which leads to oversized, heavy structures. Those practises are replaced by improvement of production and designingtechniques to utilize better properties of high strength steels. READ MORE

  6. 5. Fatigue Life Analysis of Weld Ends : Using FE-Calculations and Mechanical Testing

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Victor Ljungdahl; [2018]
    Keywords : Comparison; Effective notch method; Testing; Weld End; Jämförelse; Effective notch metoden; Provning; Svetslut;

    Abstract : Fatigue life estimation of welds is a complex issue since the characteristics of each weld are unique depending on load case, geometry and properties. Fatigue life estimation on weld ends is limited and often the weakest point of a weld. READ MORE
