"The main focus of this paper is a numerical investigation of the fracture behavior of a particulate composite (CaCO3-PP). The composite is modeled as a three-phase continuum and simulated numerically on a microscale by using finite elements. The propagation of a microcrack in a matrix filled with rigid particles covered by an interphase is analyzed. The stress distribution is determined for a variety of particle sizes and material properties of the interphase. The final results, in agreement with experimental data, confirm that the microcrack behavior depends on particle sizes." . "5"^^ . . "5"^^ . . . . "3" . . . . . . "\u0160est\u00E1kov\u00E1, Lucie" .
