    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

  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
