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

    Författare :Kent Salomonsson; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.
