  1. 1. Meso-Mechanical Modeling of Thin Adhesive Layers

    Författare :Kent Salomonsson; Högskolan i Skövde; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; adhesive layer; meso-mechanical; FEM; RVE; SEM; Engineering mechanics; Teknisk mekanik; Technology; Teknik;

    Sammanfattning : A thin adhesive layer is analyzed using a representative volume element (RVE). The RVE is comprised by, both continuum and interfacial finite elements. The interface elements allow for crack initiation and crack propagation. To obtain realistic results from the RVE simulation, an in situ scanning electron microscopy (SEM) study is performed.

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

  5. 5. Finite element methods for surface problems

    Författare :Mirza Cenanovic; Peter Hansbo; Kent Salomonsson; Paul Houston; Jönköping University; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; trace finite element method; membrane; mean curvature; level-set method;

    Sammanfattning : The purpose of this thesis is to further develop numerical methods for solving surface problems by utilizing tangential calculus and the trace finite element method. Direct computation on the surface is possible by the use of tangential calculus, in contrast to the classical approach of mapping 2D parametric surfaces to 3D surfaces by means of differential geometry operators.
