  1. 11. Implementation and validation of an isogeometric hierarchic shell formulation

    University essay from KTH/Bro- och stålbyggnad

    Author : Michael Loibl; [2019]
    Keywords : Isogeometric Analysis; Shell; Locking; Kirchho-Love; Reissner-Mindlin; Three-Dimensional Shell I;

    Abstract : Within this thesis, thin walled shell structures are discussed with modern element formulationsin the context of the Isogeometric Analysis (IGA). IGA was designed to achieve a directinterface from CAD to analysis. According to the concept of IGA, Non-Uniform RationalB-Splines (NURBS) are used as shape functions in the design and the analysis.

  3. 12. Assessment of creep damage in Fe-Ni-Cr alloys

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Frans Sorsh; [2019]
    Keywords : ;

    Abstract : It is only a matter of time before components working in high temperature environments fail due to creep. Design for creep is therefore of vital importance to maximize the lifetime of components and reduce costs that may arise from maintenance and replacement of components. READ MORE

  4. 13. Local Buckling of Doubly-Symmetric I-Sections Subjected to Warping Torsion : The limitations of the Reduced Cross-Section Method under unconventional loading

    University essay from KTH/Bro- och stålbyggnad

    Author : Miklós Ori; [2019]
    Keywords : Local plate buckling – Warping torsion – Finite element modelling - Eurocode;

    Abstract : In regular design practice, when it comes to conventional loading, such as uniaxial compression and bending, the local buckling of thin plates is taken care of through cross section classification. The effect of warping torsion, which also gives rise to normal stresses in the section, however, is typically not considered in the process. READ MORE

  5. 14. Improvements and Validation of THUMS Upper Extremity : Refinements of the Elbow Joint for Improved Biofidelity

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristín Sverrisdóttir; [2019]
    Keywords : Upper extremity; elbow; biofidelity; validation; Total HUman Model for Safety THUMS ; Finite Element Modeling FEM ; Övre extremitet; armbåge; biofidelitet; validering; Total HUman Model for Safety THUMS ; Finite Element Modellering FEM ;

    Abstract : Introduction One out of five reported motor vehicle collision injuries occur to the upper extremities. Certain parts of The Total HUman Model for Safety (THUMS) lack validation against experimental data, including the elbow. READ MORE

  6. 15. Heat transfer evaluation of a window with a ”hot box” set-up in a 18th century stone building by using COMSOL software

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : Garazi Erezkano Garai; [2019]
    Keywords : window; hot box; simulation; COMSOL; outdoor; dynamic;

    Abstract : The hot box technique is an experimental method to achieve the U-value of elements in stationary conditions; however, it is not always possible to work in stationary conditions in real world. This thesis consisted of evaluating the heat transfer of a window of a historical building with a unique hot box set-up. READ MORE
