  1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Viktor Frilén; [2023]
    Nyckelord :moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Sammanfattning : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  3. 2. 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

    Master-uppsats, KTH/Bro- och stålbyggnad

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

    Sammanfattning : 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. LÄS MER

  4. 3. Utveckling av koncept för ny åkprofil till bakgavellyft : Produktutveckling och konstruktion

    Kandidat-uppsats, Mittuniversitetet/Institutionen för kvalitets- och maskinteknik

    Författare :Gustav Fritzon; [2022]
    Nyckelord :linear motion; dimensioning; industrial production; FE analysis; linjär rörelse; dimensionering; industriell produktion; FE-analys;

    Sammanfattning : Detta examensarbete har utförts i samarbete med Z-lyften Produktion AB som tillverkar bakgavellyftar till lastbilar. En av deras modeller har funktionen att den kan köras in under lastbilen eller trailern. Lyften rullar då på hjul i så kallad slädprofiler som i sin tur är fästa mot lastbilen med ramfästen. LÄS MER

  5. 4. Strengthening of non-composite bridges by Partial Composite Action

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Johan Tjernberg; [2022]
    Nyckelord :Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

    Sammanfattning : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

  7. 5. Non-Linear strain paths in Sheet Metal Forming

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Anton Eriksson; [2021]
    Nyckelord :Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

    Sammanfattning : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. LÄS MER
