  1. 1. Non-Linear strain paths in Sheet Metal Forming

    Magister-uppsats, 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

  2. 2. Strukturella förbättringar av en markstabiliseringsmast

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Axel Skog; [2021]
    Nyckelord :ANSYS; FEA; SpaceClaim; SolidWorks; Jet-Grouting; Camatec; Scandinavian Pile Driving; ground stabilization; CAE; CAD; ANSYS; FEM; SpaceClaim; SolidWorks; Jet-Grouting; Camatec; Scandinavian Pile Driving; markstabilisering; CAE; CAD;

    Sammanfattning : This report has examined the possibilities of stiffening and strengthening a ground stabilization mast, in a way that a small production company can manufacture. The soil stabilization technique in question is Jet-Grouting also called injection drilling, which involves drilling to the desired depth and then letting high-pressure water jets mixed with filling mass to erode the surrounding soil mass and form pillars below the ground surface.

  3. 3. Towards sustainable shipping: Recommendations for the telescopic mast design of a sailing cargo vessel

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Lukas Blau; [2021]
    Nyckelord :Oceanbird; telescopic mast; conceptual design; sailing cargo vessel;

    Sammanfattning : A comparative study is carried out to investigate the most promising route towardsthe lightweight construction of a retractable mast for a sailing cargo vessel.Four design families are developed and compared. The primary criteria forjudgment are the structural mass, strength, and stiffness in relation to a providedbenchmark design. LÄS MER

  4. 4. Development of verified FE simulation method on crimp joint with gasket : A combined experimental and numerical study

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Erik Andraéy; [2021]
    Nyckelord :Method development; Radiator; Experimental Stress Analysis; Structural Analysis; Falsförband; Metodutveckling; Radiator; Experimentell Spänningsanalys; Strukturanalys;

    Sammanfattning : When developing drivetrain cooling modules for commercial vehicles, the top priority is the strength of the products. The reason lays within the structural change that companies are undergoing where the warehouses are minimized and the companies are relying on the transportation of commercial vehicles. LÄS MER

  5. 5. Compression Characteristics of Elastomer Elements

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rahul Nagaraj Dixit; [2021]
    Nyckelord :Continuum mechanics; Hyperelasticity; Mooney Rivlin; Rack and Pinion; Kontinuummekanik; Hyperelasticitet; Mooney Rivlin; Kuggstångsväxel;

    Sammanfattning : Compression of elastomer elements are nonlinear due to the cross-linked molecular structure owing to a property known as hyperelasticity. Hyperelasticity is defined as the nonlinear stress-strain behavior shown by rubber like materials which can be strained up to a range of 700% in tension and up to 40% in compression. LÄS MER
