  1. 6. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    University essay from KTH/Materialvetenskap

    Author : Christopher Hallén; Marcus Johansson Storne; [2023]
    Keywords : ;

    Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

  2. 7. Life extension of welded steel details in bridges

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Zhelei Jin; [2023]
    Keywords : Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

    Abstract : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. READ MORE

  3. 8. Cervical Hip Fractures: Trends in Surgical Treatment in Region Örebro County

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Johan Lindahl; [2023]
    Keywords : Cervical hip fracture; Arthroplasty; Osteosynthesis; Swedish Fracture Register; Mortality;

    Abstract : Introduction: Approximately 8,000 patients suffer from cervical hip fractures in Sweden every year. Recommended treatment is surgery by either osteosynthesis or arthroplasty. READ MORE

  4. 9. Experimental Testing of EPS-foam

    University essay from KTH/Hållfasthetslära

    Author : Carl Göransson; Erik Arnald; [2023]
    Keywords : Solid Mechanics; EPS; Experimental testing; Hållfasthetslära; EPS; Experimentell testning;

    Abstract : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.

  5. 10. The Influence of Roughness on Electrical Properties of Single Rock Fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yu Hou; [2023]
    Keywords : Single fracture; Roughness; Current; Electrical properties; Relative standard deviation; Numerical simulations; Enkelfraktur; Grovhet; Ström; Elektriska egenskaper; Relativ standardavvikelse; Numeriska simuleringar;

    Abstract : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. READ MORE
