Abstract

Magneto-sensitive elastomers are a class of smart materials whose mechanical properties changeinstantly by the application of magnetic field. The control of sphrerically symmetricoscillations by a homogeneous magnetic field is considered. The presented results may be usedfor generation of spherical acoustic waves.
