  1. 1. 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. 2. Numerical analysis of a bearing strength in delaminated composite joint

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

    Author : Olavi Kukkonen; [2023]
    Keywords : Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Abstract : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

  4. 3. Resistance Element Welding of Ultra High Strength Steel to Aluminium

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

    Author : Malte Eriksson; [2023]
    Keywords : ;

    Abstract : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. READ MORE

  5. 4. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  6. 5. Komplikationer vid artrodes på smådjur och ex vivo test av ett innovativt benlim för artrodeser

    University essay from SLU/Dept. of Clinical Sciences

    Author : Adam Maccormack; [2022]
    Keywords : artrodes; benlim; hund; infektion; journalstudie; karpus; katt; komplikationer; ortopedi; steloperation; tarsus;

    Abstract : En artrodes är ett operativt ingrepp som avser att genom immobilisering av en led öka den totala rörelsefunktionen i en extremitet. Efter en artrodes åstadkoms en benfusion i leden. READ MORE
