Original abstract

The main focus of this paper is the numerical investigation of fracture behaviour in particulate composite (CaCO3 -PP). The composite was modelled as a three-phase continuum and numerically simulated on a microscopic scale using finite elements. The interaction of micro-crack propagation in the matrix filled by rigid particles covered by the interphase was analyzed. Stress distribution was determined for a variety of particle sizes and material properties of the interphase. The final results, in agreement with the experimental data, confirm the dependence of microcrack behavior on particle size.

Tato práce je zaměřena na numerický popis lomového chování částicových kompozitů (CaCO3-PP). Komposit je modelován jako třífázové kontinuum. Je sledován především vliv mezivrstvy na směr šíření trhlin v matrici kompozitu.
