The dynamic hydroelasticity problem of annular channel outer wall, surrounded by elastic medium and interacting with highly viscous incompressible liquid, filling the channel, is considered. The inner wall, being an absolutely rigid cylinder of finite sizes, performs harmonic oscillations according to the assigned law. The second outer channel wall is formed by elastic cylinder shell, surrounded by...
The bending walls oscillations of slit channel set on Winkler foundation under the influence of highly viscous pulsating liquid layer are investigated. The setting and solving hydroelasticity problem made it possible to find analytical expressions of channel walls deflection and pressure in liquid, the functions of deflection amplitude distribution and liquid pressure along the channel are constructed...
The paper presents the investigation of wave occurrences of two geometrically non-linear elastic coaxial cylindrical shells model of Kirchhoff-Love type, containing viscous incompressible liquid between them, as well as inside. The difference schemes of Crank-Nicholson type are obtained for the considered equations system by taking into account liquid impact and with the help of Gröbner bases construction...
