    Sammanfattning : Paper AAbstractA numerical strategy based on the finite element method and intended for an accurate analysis of the scratch test is presented. For simplicity, but not out of necessity,the material was described by classical Mises elastoplasticity utilising large deformation theory. LÄS MER

  3. 3. Frictional Effects on Hertzian Contact and Fracture

    Författare :Denis Jelagin; Per-Lennart Larsson; Bertil Storåkers; David Hills; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact mechanics; Elastic material; Friction; Nanoindentation; Fracture; Solid mechanics; Fastkroppsmekanik;

    Sammanfattning : This thesis addresses normal axisymmetric contact of dissimilar elastic solids at finite interfacial friction. It is shown that in the case of smooth and convex but otherwise arbitrary contact profiles and monotonically increasing loading a single stick-slip contour evolves being independent of loading and profile geometry.
