1. A computerized method for creating a two-dimensional finite element model of a rubber composite of a rubber matrix and fillers, comprising a first step in which a region of the rubber matrix and a plurality of regions of the fillers are defined in a predetermined two-dimensional space, and coordinates of these regions defined are stored in a memory of a computer, a second step in which, with the computer, each of the rubber matrix's region and the fillers' regions is divided into a plurality of triangular elements, and a third step in which, with the computer, each of the triangular elements is subdivided into three quadrilateral elements, whereby the two-dimensional finite element model made up of the quadrilateral elements is created.
