The critical bending of a magnetoactive elastomer in a transverse uniform magnetic field containing magnetically soft ferromagnetic carbonyl-iron particles in an elastically soft elastomer matrix is investigated with the sample positioned vertically and with its upper-end fixed. Despite the counteracting gravitational force, a bending occurs critically with sharp peaks in the derivatives of the displacement of free end of the sample. As found, in a magnetic field, bending deformation exhibits hysteresis, which is weaker significantly than expected for a composite with an elastically soft matrix: the magnitude of the residual deformation is small, and thus, elastic effects during bending predominate over effects causing the plasticity, for instance, due to possible rheological behaviour.

Key words: smart materials, magnetoactive elastomers, carbonyl iron, magnetization, bending strain, critical bending of a magnetoactive-elastomer beam.
