摘要：

We fabricate a foil-shaped composite material based on polyurethane elastomer (PE) and magnetorheological suspension (MRS) and use it for manufacturing of plane resistors. Using the ohmmeter method, we measure the resistance R of the resistors as a function of an external magnetic field of intensity H, for various values of volume fraction Phi of MRS. Using the dipolar approximation and linear elasticity theory for small deformations, we determine the components of deformations is an element of(zz), tension sigma(zz) and magnetoelastic constant k, as a function of H and Phi. We present and discuss the obtained results. (C) 2015 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V. All rights reserved.
