    Sammanfattning : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

    Sammanfattning : In this report, the effect of external torque injection of a particular phase and frequency was analyzed using an induction motor assembly consisting of a prototype of an induction motor and a flexible mounting arrangement. The eigenfrequencies of the several components that make up the construction of the induction machine assembly are found out both by analytical and FEM methods. LÄS MER

  5. 15. FE Modelling Of Two Femur Fixation Implants

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Ali Arsiwala; Vatsal Shukla; [2021]
    Nyckelord :FEM; Femur; Image Segmentation; Material Modelling; Recon Implant; Antegrade Implant; Atypical Femoral Fracture; Intermedullary Nail;

    Sammanfattning : In the pool of women over the age of 50, the likeliness of an atypical fracture increase drastically, partly due to osteoporosis. With a pre-existing implant in the femur bone, inserted due to a prior atypical fracture, treating a later femoral neck fracture is complex and risky. LÄS MER
