  1. 31. Development of a pipeline for patientspecific finite element modelling of the left ventricle of the human heart

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Mbah Chrameh Fru; [2014]
    Nyckelord :;

    Sammanfattning : In order to perform simulations of the human heart using a heart finite element solver developed at the Computational Technology Laboratory at KTH with a data set provided by Philips consisting of surface meshes of a whole heart, the surface mesh has to be converted to a volume mesh. The conversion is manual and time consuming. LÄS MER

  3. 32. Influence of the Non-linear Effects in the Design of Viscous Dampers for Bridge Cables

    Master-uppsats, KTH/Byggvetenskap; KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Författare :Yalda Acar; Pontus Jingstål; [2014]
    Nyckelord :Bridge cables; external viscous damper; half-power bandwidth method; loss factor; non-linear vibration; Brokabel; externa viskösa dämpare; half-power bandwidt metoden; förlustfaktor; icke-linjär vibrationer;

    Sammanfattning : In this master thesis the performance of external viscous dampers attached to cables in cable-stayed bridges have been studied. A comparison has been performed between a linear and a non-linear cable model. The comparison was carried out for two bridge cables, one from the Dubrovnik Bridge and the other from the Normandie Bridge. LÄS MER

  4. 33. An Algorithm for Structural Topology Optimization of Multibody Systems

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Toheed Ghandriz; [2014]
    Nyckelord :Dymola; Abaqus; TOSCA; nonlinear Differential Algebraic Equation; finite element method; flexible body; SIMP; dynamic body; Topology Optimization of Multibody Systems; flying element; Technology and Engineering;

    Sammanfattning : Topology Optimization (TO) of static structures with fixed loading is a very interesting topic in structural mechanics that has found many applications in industrial design tasks. The extension of the theory to dynamic loading for designing a Multibody System (MBS) with bodies which are lighter and stronger can be of high interest. LÄS MER

  7. 35. Nonlinear FEM load bearing capacity assessment of a concrete bridge subjected to support settlements : Case of a continious slab bridge with angled supports

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Daniel Hansson; [2013]
    Nyckelord :Nonlinear finite element method; concrete slab brigde; support settlements; load bearing capacity assessment; angled supports; Abaqus;

    Sammanfattning : A nonlinear finite element analysis was performed for an existing road bridge in order to see if that could show a higher load bearing capacity, as an alternative to repairing or replacing. The regular linear analysis had shown that the bridge could not take any traffic load due to the effects from large and uneven support settlements. LÄS MER
