Modelling of vibration processes of viscoelastic orthotropic plates with variable rigidity
In work the problem about vibrations of viscoelastic orthotropic plates with variable rigidity is considered. The equations of vibrations concerning deflections are described by the integro-differential equations (IDE) i...
On nonlinear Pulsation of spherical Gas-bubble in noncompressible Fluid
Here is considered the problem of forced oscilation of spherical gas-bubble in viscous noncompressible Fluid. The nonlinear equation of oscilation of single bubble is obtained. The primary and secondary resonances are in...
