Method for creating finite element model of rubber composite

Abstract

A computerized method for creating a 2D or 3D finite element model of a rubber composite of a rubber matrix and fillers is disclosed. In the case of the 2D finite element model, a primary finite element model of the rubber composite is first created by defining a rubber matrix model of the rubber matrix and filler models of the fillers by the use of rectangular elements. Then, a second finite element model as the target 2D finite element model is created by moving boundary nodes positioned at boundaries between the rubber matrix model and filler models in the primary finite element model so that concavity and convexity of the surface of each filler model becomes less, whereby, in the second finite element model, some of the rectangular elements including the moved boundary nodes are deformed, but the rest of the rectangular elements are not deformed.
