Scale of professional interests
Analytical and numerical investigations of forced, parametrical and flutter type nonlinear vibrations of anisotropic plates and shells.
The occurrence of new types of resonance in forced vibrations conditioned by the non-linearity of vibrations.
The possibility of existence of stationary vibrations under the conditions of pre-critical data of velocities of flow.
The existence of lower value of critical velocity and development of methods for its evaluation.
The general theory of description of interdependent mechanical and electromagnetic processes in thin-walled bodies.
The exception of possibility of parametric resonance.
The damping of dangerous flutter type vibrations.
The essentially increment of frequency of vibrations.
The decrement of the amplitude of vibrations more than hundred times with the help of constant magnetic field.
The generation of famous formula of the "Pump theory".
The possibility of excitement of forced and parametric types resonant vibrations with the help of nonstationary magnetic field.
The control of behavior of parametric vibrations with the help of constant magnetic field.
The optimal control of dependence of amplitude on frequency of nonlinear vibrations, a magnetic field is being present.
The theoretical aspects of propagation of dependent magnetoacoustic waves in piezomagnetic and magnetostrictive media.
The possibility of generation of new type shear surface and crack waves conditioned by piezomagnetic (or magnetostrictive) effects.
The possibility of generation of accompanying surface vibrations and as a result the possibility of transmission of acoustic waves from one piezomagnetic medium to another one without any mechanical contact.
Methods for mathematical modelling and solution for some problems were developed, that have important applied importance, particularly for problems of strength, stability and vibrations of superconductive and magnetosoft ferromagnetic bodies placed in stationary and non-stationary magnetic fields.
