Abstract

The possibility to determine the magnetostriction coefficient a of a magnetoactive elastomer is theoretically demonstrated by way of simple isometric experiment, when the force is measured that emerges in result of application of a field in the direction along which the dimension of the sample is fixed. It is shown that the value of a may be found from analyzing the dependence of the force (or surface pression) on the aspect ratio of the sample.
