Method for creating finite element model of rubber composite

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 triangular elements and primary quadrilateral elements wherein the number of the primary quadrilateral elements is less than the number of the triangular elements, and
• a third step in which, with the computer, each of the triangular elements is subdivided into three quadrilateral elements, and each of the primary quadrilateral elements is subdivided into four quadrilateral elements, whereby the two-dimensional finite element model made up of the quadrilateral elements is created.

A computerized method for creating a three-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 three-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 tetrahedral elements, and
• a third step in which, with the computer, each of the tetrahedral elements of the rubber matrix's region and fillers' regions is subdivided into four hexahedron elements, whereby the three-dimensional finite element model made up of the hexahedron elements is created.
