Issue of modeling of particulate composites
 Hutař, Pavel ; Náhlík, Luboš
The paper is focused on micro-mechanical modeling of particulate composites with polymer matrix. A composite with CaCO3 particles is modeled as three phase continuum in the work. The global effective mechanical properties of the composite are estimated on the base of knowledge of mechanical properties of individual constituents. Different size, distribution and material properties of the particles are taken into account. The paper can contribute to the better estimation of macro-mechanical properties of polymer matrix composites.

Computation of the internal stress and strain fields in the microstructural level of the studied composite and understanding of microcracks behaviour in the interaction with particles is the first step to understanding the global behaviour of the composite based on microstructural morphology. Therefore, particle reinforced composite has been modelled as a three-phase material with homogenously distributed coated particles and numerically studied on the microscopic scale using finite element modelling. The FEM modelling and unit cell models provide an effective tools for parametric study of the three-phase composite mechanical properties.
