  1. 1. FE-modelling of glulam connection in a pre-tensioned glulam truss : Detailed Finite element modelling of the connection between primary beam and compression stud in a sub-tensioned glulam roof truss

    University essay from KTH/Bro- och stålbyggnad

    Author : Edward Sebastian Swaretz; [2022]
    Keywords : Glulam; sub-tensioned roof truss; connection; instability; Abaqus Standard; Finite element method;

    Abstract : After the collapse of the roof structure in Tarfalahallen 2020, great attention has been focused on instability of sub-tensioned glulam roof trusses. Investigations were launched to find the reason for the collapse and the cause was instability in the roof truss that supported the roof. READ MORE

  2. 2. Adhesive bonding of fiber laminate patch to sandwich-structured composite

    University essay from Lunds universitet/Materialteknik

    Author : Daniel Nesic; [2022]
    Keywords : Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

    Abstract : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. READ MORE

  3. 3. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

    University essay from KTH/Hållfasthetslära

    Author : Philip Singh; [2022]
    Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

    Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

  4. 4. Elasticities of demand in the Swedish electricity market : A quantitative study of the price- and income elasticity of electricity demand of the four different price areas in Sweden

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Melker Eriksson Lind; Sebastian Heikurainen; [2022]
    Keywords : ;

    Abstract : The Swedish electricity market was divided into four different electricity price areas in 2011 which has led to regional differences in prices in Sweden in the recent years. The electricity prices have also started to rise considerably in the past years, which has led to questions around the subject taken a bigger place in the political debate. READ MORE

  5. 5. Structural Dynamics at Higher Frequencies using the Finite Element Method : Assessment of Solver Algorithms and Component Mode Synthesis for Dynamic Response Analysis of Large Structures

    University essay from KTH/Hållfasthetslära

    Author : Khashaiar Noushin; [2022]
    Keywords : ;

    Abstract : Scania is making a transition from traditional combustion engines to electric vehicles and therefore developing methodology for high frequency analysis of large structures. The computational time size of results files are impractically high, making any analysis infeasible. READ MORE
