Originální abstrakt

The main focus of a present paper is an estimation of the macroscopic stress-strain behavior of a particulate composite. The particulate composite with a crosslinked polymer matrix in a rubbery state filled by an alumina-based mineral filler is investigated by means of the finite element method. A hyperelastic material behavior of the matrix is modeled by the Mooney-Rivlin material model. Numerical models on the basis of unit cells are developed. An assumption of the existence of the discontinuity (breaking) in the matrix at higher loading levels is taken into account to obtain a more accurate estimation of the stress-strain behavior of the particulate composite investigated. The numerical results obtained are compared with experimental stress-strain curve and good agreement has been found. The paper can contribute to a better understanding of the behavior and failure of particulate composites with a polymer matrix.
