1. 1. Influence of hydrogen and carbides on high temperature cracking in cast Inconel

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Gunnar Dufwa; [2022]
   Keywords : Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

   Abstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE

3. 2. 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

4. 3. FEM model of impacts on blades

   University essay from KTH/Kraft- och värmeteknologi

   Author : Lore Ricquemaque; [2016]
   Keywords : ;

   Abstract : In-service support engineers often have to answer derogations requests regarding impacts on compressor blades. The stress concentration factor is a physical quantity helping them to take the decisions : it is a measure of the local increase of the stress due to the impact. READ MORE
