MAGNETOELASTIC FORCED AND FREE VIBRATIONS OF FERROMAGNETIC PLATES IN DIRECT TRANSVERSE OR LONGITUDINAL ELECTROMAGNETIC FIELDS

摘要

The experimental investigations of the problem of bending vibrations of magnetoelastic and ferromagnetic plates are carried out. The amplitudes of displacements, velocities and accelerations are evaluated and the corresponding curves as functions of the magnetic field, longitudinal or transverse, are drawn. It is shown that they have extremal character. Also graphs of frequencies of free vibrations of plates as functions of magnetic field are given, what is in agreement with the spatial theory developed by ourselves.
