Numerical Assessment of Electrical and Magnetic Characteristics of Elastomer Composites

The paper presents algorithms for solving boundary value problems of electrical conductivity and magnetostatics for a cell of elastomeric composite materials (ECMs) by the finite element method. The algorithms enable one to determine both potential and strength of electromagnetic fields which are relevant in the development of the ECMs with specified functional properties. The values of electrical conductivity and magnetic permeability have been calculated by comparing their integral levels for the ECM cell (electromagnetic field energy and heat power loss) with those of the equivalent homogeneous material.
