Abstract
In this paper the issues of dynamic stability of three-layered magntostrictive ferromagnetic plate under the action of harmonic in time transversal magnetic field are studied. Having solved the certain problem in this paper it is established, that due to the magnetostrictive properties of plate material it is possible to generate resonant vibrations of parametric type (possibility of loss of dynamic stability) in the examined plate under the action of harmonic in time magnetic field. The influences of heterogeneity and magnetostrictive properties of the plate on the exaamined areas is studied, also.
