Pendulum waves on the surface of block rock mass under dynamic impact
Nadezhda Aleksandrova
Under numerical investigation is propagation of surface pendulum waves in 3D block medium. The medium is modeled by 3D lattice of masses connected with elastic springs and viscous…
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…
Deformations of one-dimensional block media
Nadezhda Aleksandrova
The paper gives a description of wave propagation in discrete-periodic one-dimensional media with block structure. For one-dimensional problems mathematical models are proposed tha…
The discrete Lamb problem: Elastic lattice waves in a block medium
Nadezhda Aleksandrova
We study the propagation of transient waves under the action of a vertical step point load on the surface of a half-space filled by a block medium. The block medium is modeled by a…
Numerical-analytical investigation into impact pipe driving in soil with dry friction. Part II: Deformable external medium
Nadezhda Aleksandrova
Under analysis is travel of P-waves in an elastic pipe partly embedded in soil with dry friction. The mathematical formulation of the problem on impact pipe driving in soil is base…
Numerical-analytical investigation into impact pipe driving in soil with dry friction. Part I: Nondeformable external medium
Nadezhda Aleksandrova
The study focuses on propagation of longitudinal waves in an elastic pipe partly embedded in a medium with dry friction. Mathematical formulation of the problem on the impact pipe…
