  1. 1. Exploring State-of-the-Art Machine Learning Methods for Quantifying Exercise-induced Muscle Fatigue

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Abboud Afram; Danial Sarab Fard Sabet; [2023]
    Nyckelord :EMG; SEMG; STFT; CWT; SVM; CNN; GAN; DCGAN; BCE; SGD; deep learning; machine learning; muscle fatigue; DCGAN; spectrogram; CNN models; transfers learning; data augmentation; feature extraction;

    Sammanfattning : Muscle fatigue is a severe problem for elite athletes, and this is due to the long resting times, which can vary. Various mechanisms can cause muscle fatigue which signifies that the specific muscle has reached its maximum force and cannot continue the task. LÄS MER

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

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Sammanfattning : 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. LÄS MER

  4. 3. Tillverkning och individanpassning av ortopediska skoinlägg med additiv tillverkning

    M1-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Hanna Haegermarck; Henrik Tyrfors; [2023]
    Nyckelord :Ortopediska inlägg; Materialextrudering; Termoplastisk Polyuretan TPU ;

    Sammanfattning : This thesis was made in collaboration with Aktiv Ortopedteknik’s clinic in Västerås, they are knowledgeable about orthopedic products individually customized for their customers. They have examined the possibility of 3D printed orthotics with need for hard support, but so far, the technology for softer orthotics like shoe insoles has not been explored. LÄS MER

  5. 4. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth

    Master-uppsats, Karlstads universitet

    Författare :Hasan Majid; [2022]
    Nyckelord :;

    Sammanfattning : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. LÄS MER

  7. 5. Methodology for Obtaining S-N Curves using Fatigue Testing and Static FEA

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Filip Anderfelt; David Äse; [2022]
    Nyckelord :Fatigue; Testing; Fatigue Testing; Test rig; Pneumatic; FEA; Weld; Steel; Fillet Weld; S-N curve;

    Sammanfattning : The use of recommended S-N curves, presented in current literature, to analyse and determine the fatigue life of a part is common practice in, inter alia, the construction industry.However, the recommended S-N curves are generally created for larger components used in mainly the construction industry.
