The paper considers the static pressure of the
environment on the parallel pipe. The environment is elastic and homogeneous bodies. To determine the ambient
pressure, the finite element method is used. An algorithm was developed and a
computer program was compiled. Based on the compiled program, numerical results
are obtained. The numerical results obtained for two to five parallel pipes are
compared wit ...

The propagation of natural
waves in a cylindrical shell (elastic or viscoelastic) that is in contact with
a viscous liquid is considered. The problem reduces to solving spectral
problems with a complex incoming parameter. The system of ordinary differential
equations is solved numerically, using the method of orthogonal rotation of
Godunov with a combination of the Muller method. The dissipative processes in
the mechanical system ...

The vibrations of deformed bodies interacting with
an elastic medium are considered. The
problem reduces to finding those values of complex Eigen frequencies for which
the system of equations of motion and the radiation conditions have a nonzero
solution to the class of infinitely differentiable functions. It is shown that
the problem has a discrete spectrum located on the lower complex plane and the
symme ...

In this paper, a conjugate spectral problem and
biorthogonality conditions for the problem of extended plates of variable
thickness are constructed. A technique for solving problems and numerical
results on the propagation of waves in infinite extended viscoelastic plates of
variable thickness is described. The viscous properties of the material are
taken into account using the Voltaire integral operator. The investigation is
carr ...

The response to stress delivered by a nonisochoric hollow cylinder is
critical to its future life and integrity. The design of cylinders must
emphasize durability; therefore, the knowledge of the yield stress of the
constituent material is essential. The stress component of a pressurized
compressible circular cylinder made of nonlinearly elastic material was
considered here and the yield stress was determined.
