Original Abstract

The main objective of this paper is the numerical investigation of fracture behavior in polymer particulate composites. In this paper the composite was modeled as a three-phase continuum – the matrix, particles and interphase. Mechanical response was analyzed, as well as the interaction of micro-crack propagation in the matrix filled by rigid particles covered by the interphase. Computations were done for a variety of material properties of the matrix and the interphase using the finite element commercial code ANSYS. It was concluded that specific configurations of the interphase properties can lead to a better understanding of the connection between stiffness and fracture toughness. Linear elastic fracture mechanics was used for the calculations.
