Transient longitudinal waves in 2D square lattices with Voigt elements under concentrated loading
Nadezhda I. Aleksandrova
The aim of this article is to study the attenuation of transient low-frequency waves in 2D lattices of point masses connected by Voigt elements, under an antiplane concentrated loa…
The propagation of transient waves in two-dimensional square lattices
Nadezhda I. Aleksandrova
The aim of this article is to study the attenuation of transient low-frequency waves in 2D lattices in both plane and antiplane problems. The main idea of this article is that anal…
On the asymptotics of integrals arising in the study of the wave motion in lattices
Nadezhda I. Aleksandrova
We present a method for finding the asymptotics of integrals arising in solid mechanics.
Influence of soil plug on pipe ramming process
Nadezhda Aleksandrova
Different modes of advance of a pipe with a soil plug under rectangular impulse are investigated numerically and analytically with regard to dry friction between the pipe and plug…
Propagation of pendulum waves under deep-seated cord charge blasting in blocky rock mass
Nadezhda Aleksandrova
The object of the numerical study is the travel of pendulum waves in a blocky medium under nonstationary impact of deep-seated charge blasting on the surface of the expansion chamb…
Asymptotic formulae for the Lommel and Bessel functions and their derivatives
Nadezhda Aleksandrova
We derive new approximate representations of the Lommel functions in terms of the Scorer function and approximate representations of the first derivative of the Lommel functions in…
Asymptotic solution of the anti-plane problem for a two-dimensional lattice
Nadezhda Aleksandrova
Propagation of unsteady waves under the effect of a step point load on a square lattice of spring-connected masses is investigated. The problem is solved by two methods. Asymptotic…
