The magnetoelastic vibrations of ideal conductive rectangular plate in longitudinal magnetic field with initial magnetic impulse
Based on the theory of Kirchhoff’s plate is solved a problem of vibrations of magneto-elasticity with initial conditions. The frequency values of vibrations are obtained depending on the magnetic field.
Dependence «amplitude-frequency» of non-linear flutter type oscillations of plates in pre-critical stage
The problem of nonlinear oscillations of an isotropic rectangular plate in a supersonic gas flow is examined. The study was conducted taking into account both types of nonlinearities: wind (quadratic and cubic) and geome...
About two-dimensional equations of two-layer anisotropic plate when the layers interact by law dry friction
Asymptotic method is applied and two dimension differential equations with partial derivatives from geometrically nonlinear equations of three dimension problem of elasticity theory for two-layer anisotropic plate are re...
