The paper presents a mechanical and mathematical model, developed by the author for study of dynamical behavior tamping rammer. At first, some aspects related to compaction soil construction works are presented. In this study, was modeled using Kelvin–Voigt model. To validate program written in C language, that allows analyze parameters influence operation rammer, developed. Three constructive ...

In this manuscript, exact solutions of the Oskolkov equation, which describes dynamics incompressible viscoelastic Kelvin-Voigt fluid, are presented. The -expansion method is used to search for these solutions. obtained analyzed with help appropriate parameters and presented graphics. applied efficient reliable fundamental nonlinear waves that enrich various dynamical models seen in engineering...

In this paper, we study the stability problem of a star-shaped network elastic strings with local Kelvin-Voigt damping. Under assumption that damping coefficients have some singularities near transmission point, prove semigroup corresponding to system is polynomially stable and decay rates depend on speed degeneracy. This result improves rate associated an earlier Z. Liu Q. Zhang in [21] involv...
