  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. Mechanical properties of SiC nanowires with polytypes

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Anders Vesti; [2019]
    Keywords : atomistic modeling; nanowires; molecular dynamics; simulation; SiC; silicon carbide; fracture behavior; nanomechanics; Physics and Astronomy;

    Abstract : In this report, we model the mechanical properties and fracture behavior of SiC nanowires with different polytypes using Molecular Dynamics (MD) simulations. The mechanical properties investigated are the Young’s modulus, the maximum tensile stress and the fracture strain. The three polytype tested are SiC (3C), (2H) and (4H). READ MORE

  4. 3. The urban poor at a crossroads: exploring speculative urbanisation dynamics in Addis Ababa’s social housing programme

    University essay from Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/LUMID International Master programme in applied International Development and Management

    Author : Gurkan Ongel; [2019]
    Keywords : Addis Ababa; Integrated Housing Development Programme; speculative urbanisation; gentrification; relocation; dislocation; spatial justice; urban poor; urban transformation; economic and social inequality; Ethiopia; Social Sciences;

    Abstract : This thesis reviews the impact and relevance of the Integrated Housing Development Programme (IHDP) on the economic and social wellbeing of the urban poor in Addis Ababa, Ethiopia. By situating the programme’s performance from the perspective of its residents and the urban poor in speculative urbanisation theory, the study investigates the urban transformation dynamics it has created.
