  1. 16. Pilot Testing of a Hydraulic Bridge Exciter

    University essay from KTH/Bro- och stålbyggnad

    Author : Richard Borg; Olivier Dymén; [2015]
    Keywords : Hydraulic bridge exciter; controlled excitation; modal testing; experimental modal analysis; railway bridges; measurements; load shaker; FEM; FE-modelling; script; Hydraulisk broexciterare; kontrollerad excitering; modala tester; experimentell modal analys; järnvägsbroar; mätningar; lastexciterare; FEM; FE-modellering; script;

    Abstract : In the design of a railway bridge that is meant for train speeds larger than 200 km/h, the Swedish Traffic Administration requires a dynamic analysis in addition to the conventional static design. The models used for static design may not always be suitable for dynamic analysis, which could lead to inaccurate estimations of the dynamic response. READ MORE

  3. 17. Evaluation of a Tramway’s Track Slab in Conventionally Reinforced Concrete or Steel Fibre Concrete

    University essay from KTH/Betongbyggnad

    Author : Stavros Zioris; Alija Vranjkovina; [2015]
    Keywords : Steel fibre reinforced concrete SFRC ; conventional reinforcement; finite element;

    Abstract : The dominant reinforcement used widely for concrete structures is conventional steel bars (rebars). Nevertheless, the perpetual effort toward evolution and development could not exclude the engineering field, thus new innovative and sophisticated methods are introduced. READ MORE

  4. 18. Study of dens fracture in the elderly and the influence of osteoporosis with a finite element model

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Marco Antonio Marra; [2013]
    Keywords : biomechanics trauma finite element neck injuries;

    Abstract : Cervical spine injuries are a serious threat, as they may damage the central nervous system. In the elderly, cervical fractures due to falls are very frequent. The overall weakening of the bony and ligamentous spine decreases the resistance to fractures. READ MORE

  5. 19. Mechanical properties of materials made of nano-cellulose

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Denoyelle Thibaud; [2011]
    Keywords : nano-cellulose; paper mechanics;

    Abstract : Recent experimental findings have demonstrated great mechanical properties of nanopaper compared to ordinary paper. In this work, we have studied the formation of the elastic modulus of paper. Our goal was to investigate the contribution of fibers, fiber bonds and network structure. READ MORE

  6. 20. Optimisation of the Ektorp sofa frame through the use of Finite element analysis

    University essay from Akademin för innovation, design och teknik

    Author : Anders Rundgren; Fredrik Wörmke; [2011]
    Keywords : Finite element analysis; Product development; FEA; FEM; Design; Optimization; Sofa frame; IKEA; Wood; SolidWorks Simulation; CAD; Finit element analys; Produktutveckling; FEA; FEM; Konstruktion; Optimering; Ram; Soffa; IKEA; Trä; SolidWorks Simulation; CAD;

    Abstract : The interest in using finite element analysis (FEA) as a product development tool is present within IKEAof Sweden (IoS). To gain additional support from within IoS a project was issued to identify the meritsand demerits of FEA. This was done by applying FEA to optimise an existing product, namely theEktorp sofa frame.
