Elastic waves in continuous and discontinuous geological media by boundary integral equation methods: A review
George D. Manolis,Petia Dineva +1 more
TL;DR: A review of boundary integral equation (BIE) based methods for the numerical modeling of elastic wave motion in naturally occurring media is presented in this article, where the main reason for using BIE is the presence of the free surface of the earth, whereby large categories of problems involve continua with a small surface to volume ratio.

Seismic response of lined tunnels in the half-plane with surface topography
TL;DR: In this paper, the seismic response of multiple tunnels reinforced with liners and buried within the elastic homogeneous half-plane in the presence of surface relief is examined, and the results of these parametric studies reveal the influence of the following key parameters on the soil-tunnel system response: (a) the shape of the free-surface relief; (b) the depth of placement of the tunnels and their separation distance; (c) the SH-wavelength to tunnel diameter ratio; (d) the elastic properties of the tunnel lining rings and (e) the dynamic

Seismic Wave Propagation in Stratified Media
TL;DR: In this paper, the authors focus on elastic wave propagation in stratified media and show how the excitation of elastic waves, within a horizontally stratified structure, can be conveniently developed in terms of reflection and transmission matrices.

Boundary elements in dynamics
TL;DR: In this paper, the authors propose a dual reciprocity approach for transient elastodynamics: boundary integral formulation transformation of the domain integral, which transforms the boundary integral into a transformation of domain integral transformation.

On the Green's functions for a layered half-space. Part II
Randy J. Apsel,J. Enrique Luco +1 more
TL;DR: In this paper, a numerical procedure to obtain the dynamic Green's functions for layered viscoelastic media is presented based on numerical evaluation of certain Hankel-type integrals which appear in an integral representation derived previously by the authors.
