Оn a problem of axis-symmetric vibrations of circular cylindrical shell
The model of vibration equations of cylindrical shell with regard to microrotations and transversal shears is suggested. The frequency of membrane, bending and rotational vibrations are determined.
On the Forms of Nonlinear Propagation of High-Frequency Perturbation in a Thermal Relaxing Gas-Liquid mixture
The quasyadiabatic and quasyisothermic regimes of propagation of highfrequensy perturbation are considered in a thermal relaxing gas–fluid mixture. The simplified nonlinear equations are obtained. It is shown that in the...

The Problem of Bending of Rectangular Plate Taking into Account the Transversal Shear
In this work the problems on the bending of rectangular plate on the basis of classical theory by Kirchhoff and Ambartsumyan’s theory is observed. It is shown, that when the plate is leaned free on two opposite sides, an...
