  1. 1. Finite element modelling of strained nanowire heterostructures

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Alexander Grape Wyke; [2019]
    Keywords : Strain; nanowire; heterostructure; physics; nanophysics; COMSOL; simulation; lattice; Physics and Astronomy;

    Abstract : When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. READ MORE

  2. 2. A SIMULATION WITH FINITE ELEMENTS TO MODEL STEEL SHEET SLITTING : A Master Thesis in Engineering Physics

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Adam Ahlgren Peters; [2019]
    Keywords : Finite element Method; steel; steel shearing; high performance steels; Finita Element Metoden; FEM; stål; stålklippning; höghållfasta stål; industriell ståltillverkning; spaltning;

    Abstract : A steel slitting process is simulated using FEM (Finite Element Method) in order to see potential defects along the edge in a steel sheet after it has been cut. The model's results were compared to microscope images of the steel sheet in order to verify accuracy. READ MORE

  3. 3. Simulation of distributed windings using the insert technique

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap; Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Hue Hoang; Matilda Widerström; [2019]
    Keywords : Abaqus CAE; Simulation; Insert technique; Electric motor; Stator; Explicit finite element method; Windings; FEM; Abaqus CAE; Simulation; Insert technique; Elektrisk motor; Stator; Explicit finit elementmetod; Lindningar; FEM;

    Abstract : During the insert process when the windings of an electric motor are pushed into the stator slots, some detrimental phenomena can occur that affect the efficiency and life of the motor. To detect these phenomena and optimize the process, a simulation would be useful. READ MORE

  4. 4. Modelling cross-laminated timber floors in dynamic analysis - Eigenfrequency prediction

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Johannes Wetterholt; [2019]
    Keywords : finite element method; FEM; dynamic analysis; Eigenfrequency; CLT; cross-laminated timber; cross-laminated timber floors; wooden floors; Technology and Engineering;

    Abstract : In the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials.

  5. 5. Simulation of Delamination Migration in Laminated Composite Structures - An Approach Combining Extended Finite Elements and a Cohesive Zone Model

    University essay from Lunds universitet/Hållfasthetslära

    Author : Viktor Björklund; [2018]
    Keywords : Crack propagation modeling; Fiber-reinforced polymer; Laminated composites; FRP; CFRP; Cohesive zone model; CZM; Delamination migration; FEM; XFEM; Fracture mechanics; Progressive damage modeling; Surface-based cohesive behaviour; Technology and Engineering;

    Abstract : Fiber-reinforced polymer matrix composites are being used increasingly in lightweight applications where high strength and stiffness is required. One of the main challenges with designing components from such materials is to predict the ultimate strength and behaviour of the structure. READ MORE
