Model of block media taking into account internal friction

N. I. Aleksandrova

The block medium is modeled by a discrete-periodic spatial lattice of masses connected by elastic springs and viscous dampers. To describe the viscoelastic behavior of the interblo…

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…

Seismic waves in a three-dimensional block medium

Nadezhda Aleksandrova

We study numerically the propagation of seismic waves in a three-dimensional block medium. The medium is modeled by a spatial lattice of masses connected by elastic springs and vis…
