  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. 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

  3. 3. Impact of Sidewall Pressure on High Voltage Cables

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Robin Berglind; [2018]
    Keywords : High Voltage Cable; Contact Mechanics; Finite element anlysis and Pressure film;

    Abstract : When a high voltage cable is transported throughout factory it is affected by sidewall pressure in cable bends between the roller supports and the cable. The problem is when the sidewall pressure is too high it will deform the cable which can have a negative impact on the conductivity of the cable. READ MORE

  4. 4. Simulations of contact mechanics and wear of linearly reciprocating block-on-flat sliding test

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

    Author : André Rudnytskyj; [2018]
    Keywords : Modelling; Contact mechanics; Wear; Sliding test;

    Abstract : The use of computational methods in tribology can be a valuable approach to deal with engineering problems, ultimately saving time and resources. In this work, amodel problem and methodology is developed to deal with a common situation found in experiments in tribology, namely a linearly reciprocating block-on-flat drysliding contact.

  5. 5. Structural and tribological analysis of harvester crane joint

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

    Author : Gabriel Hedström; [2018]
    Keywords : Forest machine; Harvester; Grease-lubricated journal bearing; Lubrication; Contact mechanics; Wear; Friction; Finite element;

    Abstract : Grease-lubricated journal bearings are widely used in heavy duty applications, such as construction equipment, agriculture- and forest machines. The main purpose of the grease-lubricated journal bearing is solely to create sustainable rotation of a given application. However, purpose seldom decides complexity of journal bearing design.
