  1. 1. A Lagrangian-Eulerian simulation method for viscoelastic flows applied to adhesive joining

    Författare :Simon Ingelsten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volume of fluid; computational fluid dynamics; immersed boundary methods; viscoelastic flow; adhesive joining;

    Sammanfattning : Viscoelastic flows are important for many industrial processes, such as adhesive joining, polymer extrusion and additive manufacturing. Numerical simulations enable virtual evaluation and product realization, which can support the design phase and reduce the amount of costly physical testing. However, such applications are challenging to simulate. LÄS MER

  3. 2. Meso-Mechanical Modeling and Analysis of Adhesive Layers

    Författare :Kent Salomonsson; Ulf Stigh; Per Ståhle; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive layer; Meso-mechanical; Representative Volume Element; Large curvatures; Interphase elements; Evolution algorithm; Engineering mechanics; Teknisk mekanik; Technology; Teknik;

    Sammanfattning : This thesis is concerned with the modeling, simulation and analysis of adhesive layers. By use of an in situ scanning electron microscopy study it is found that the adhesive studied in the present thesis has a very complex structure with two different compounds, a mineral and an epoxy/thermoplastic blend.
