This paper introduces a novel method of modelling acoustic and elastic wave propagation in
inhomogeneous media with sharp variations of physical properties based on the recently …

In this chapter, a family of grid-characteristic methods for numerical simulation is considered.
These methods are developed and used to solve a wide range of applied problems …

The initiation of seismic activity on the continental shelf and its destructive effect on
composite oil pipelines laid on the seabed is modeled numerically. The dynamic behavior of …

The grid-characteristic numerical method (GCM) for hyperbolic equations systems is applied
in many science fields—gas dynamics, hydrodynamics, plasma dynamics, etc. Its application …

An advantage of the discontinuous Galerkin method is the ability to describe complex
contact surfaces by using unstructured computational grids. However, the use of the …

Low-velocity strikes are considered as one of the most dangerous load types for composites,
especially in aviation. They do not lead to an immediate destruction of a whole detail, but …

Fracturing is the fundamental quality of real rocks, their most important characteristic, the
subject of research and the source of information about the geological environment and oil …

Polymer composites are reinforced with one or several metal layers to increase the strength
of parts made of composites. This work is devoted to modeling the behavior of such …

In this chapter, the application of the grid-characteristic method to solving seismic
prospecting problems is considered. The characteristic seismogeological models, including …

Seismic waves propagating in a fractured geological medium are numerically simulated.
Their dynamic behavior is described using a linear elastic model with an explicit description …
