  1. 11. Modeling aspects of reliability-based design of lined rock caverns

    Författare :Davi Rodrigues Damasceno; Fredrik Johansson; Johan Spross; Rafael Jimenez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lined rock cavern; reliability-based design; analytical modeling; finite element modeling; underground gas storage; Inklädda bergrum; tillförlitlighetsbaserad design; analytisk modellering; finita elementmodellering; underjordisk gaslagring; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : The storage of large quantities of hydrogen gas in underground lined rock caverns (LRCs) could contribute to an efficient supply of fossil-free energy. The consequences of failure of such storage can be catastrophic, so representative predictive models and a small probability of failure are needed for the LRC design. LÄS MER

  3. 12. Behaviour and resistance of composite slabs : experiments and finite element analysis

    Författare :Milan Veljkovic; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Composite slab flooring systems are used in steel framed buildings as well as in conjunction with concrete, prestressed concrete and timber structures. Composite slabs consist of a thin-walled profiled steel sheet, reinforcement and in-situ cast concrete. LÄS MER

  4. 13. A generalized finite element method for linear thermoelasticity

    Författare :Anna Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermoelasticity; parabolic equations; linear elasticity; multiscale; composites; generalized finite element; local orthogonal decomposition; a priori analysis; a priori analysis;

    Sammanfattning : In this thesis we develop a generalized finite element method for linear thermoelasticity problems, modeling displacement and temperature in an elastic body. We focus on strongly heterogeneous materials, like composites. LÄS MER

  5. 14. Development of an Anisotropic Finite Element Head Model for Traumatic Brain Injury Prediction

    Författare :Chiara Giordano; Svein Kleiven; Songbai Ji; KTH; []
    Nyckelord :Axonal Strain; Brain Anisotropy; Traumatic Brain Injury; Finite Element Analysis; Brain Tissue; Constitutive Modeling.; Medical Technology; Medicinsk teknologi;

    Sammanfattning : Traumatic brain injury (TBI) is a worldwide health care problem with very high associatedmorbidity and mortality rates. In particular, the diagnosis of TBI is challenging: symptomsoverlap with other pathologies and the injury is typically not visible with conventionalneuroimaging techniques. LÄS MER

  7. 15. A moving boundary problem for capturing the penetration of diffusant concentration into rubbers : Modeling, simulation and analysis

    Författare :Surendra Nepal; Adrian Muntean; Yosief Wondmagegne; Magnus Ögren; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moving boundary problem; finite element method; a priori error estimate; a posteriori error estimate; order of convergence; diffusion of chemicals into rubber; swelling; Matematik; Mathematics;

    Sammanfattning : We propose a moving-boundary scenario to model the penetration of diffusants into rubbers. Immobilizing the moving boundary by using the well-known Landau transformation transforms the original governing equations into new equations posed in a fixed domain. LÄS MER
