Propagation of Natural Waves on Plates of a Variable Cross Section

Abstract: 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 carried out within the framework of the spatial theory of viscoelasticity. The techni… Show more

“…In the case of an inhomogeneous system (R E2 =0) The role of the global damping coefficient is imaginary parts of both the first and second frequencies ( Figure 5). The mathematical and physical aspects of this effect are explained in [13,14,15,16]. The change in the parameter, on which the global coefficient of damping depends so substantially, can be achieved by varying the geometric dimensions or physical properties, thereby opening up the perspective possibility of effectively controlling the damping characteristics of dissipatively inhomogeneous viscoelastic systems.…”

“…In a number of works, for the control of linearly extended objects, the use of a rod wave is proposed to give rise to the minimum velocity dispersion and torsion wave mode, in which there is no dispersion [1,2]. As an informative parameter in the waveguide control of linearly extended objects, as a rule, the reflection coefficient is used.…”
