  1. 16. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique

    University essay from KTH/Hållfasthetslära

    Author : Gustav Thessén; [2022]
    Keywords : µ-CT modelling; phase-field method; bio-glass scaffolds; strength assessment; Mikrotomografi; μ-CT; fasfältsmetoden; bio-glas stödstrukturer; brottgräns;

    Abstract : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.

  3. 17. Swingarm and Rear Suspension Design in an Electric Reverse Trike

    University essay from Lunds universitet/Innovation

    Author : Hannes Nilsson; [2022]
    Keywords : Swingarm; Trike; Topology optimisation; Topology optimization; FEM; Finite Element Method; FEA; Finite Element Analysis; Technology and Engineering;

    Abstract : OMotion AB is developing a new model of their vehicle that will house a more powerful motor than the current model, which uses a hub motor in the rear wheel. The motor will be mounted behind the seats in the rear of the vehicle, entailing that drive by either chain or belt will be necessary. READ MORE

  4. 18. Micro- / Meso- Scale Dielectric Strength Testing of Fibre Composites

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johannes Fernberg; [2022]
    Keywords : Dielectric strength; composite; GFRP; glassfibre; composite microstructure; FEA; electric breakdown; single fibre;

    Abstract : Glass fibre composites are common materials used in high voltage applications as insulating materials that provide good structural integrity. The aim of this thesis is to develop a method of studying the failure in such materials by measuring the dielectric strength on micro- and meso- scale samples, consisting of single fibre filaments and fibre bundles respectively embedded in epoxy resin.

  5. 19. Design and evaluation of a shock load resistant dynamic chain plate

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Daniel Olsson; [2022]
    Keywords : Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Abstract : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. READ MORE

  6. 20. Dynamic Analysis of a Window connected via the Click-In System

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Abhikaran Bhatia; [2022]
    Keywords : Finite Element Modelling; Vibrational Analysis; MSC Nastran; MSC Apex;

    Abstract : It is often needed to predict the behavior of structures. With the helpof an FE model, it is possible to see the motion of the structure. Inthis, Master thesis work time domain analyses were carried out on afinite element model representing a window attached by click-ins. READ MORE
