  • Influence of the cell geometry on the tensile strength of open-cell ceramic foams 

    Ševeček, Oldřich; Papšík, Roman; Majer, Zdeněk; Kotoul, Michal (Elsevier, 2020-02-19)
    Nowadays used open cell foam ceramic materials are mostly of irregular structure which means that the shape of particular foam cells does not exhibit any regular pattern. On one hand, such foam structures lead to only very ...
  • Understanding the edge crack phenomenon in ceramic laminates 

    Ševeček, Oldřich; Kotoul, Michal; Leguillon, Dominique; Martin, Éric; Bermejo, Raul (Gruppo Italiano Frattura, 2015-10-05)
    In this work, a 2D parametric finite element model has been developed to predict the onset and propagation of an edge crack in ceramic laminates using a coupled stress-energy criterion. This approach states that a crack ...
