Generalization of Rayleigh's high-frequency theory for the 2D Helmholtz equation in a half-space subject to a radiation condition at infinity and a Dirichlet condition on a 1D periodically-uneven boundary
Armand Wirgin
The 2D Helmholtz equation, radiation condition and Dirichlet boundary condition, are the translation, in mathematical terms, of (at least) three physical 2D problems for the predic…
Resonant Seismic Motion Within a Sedimentary Basin Revisited
Armand Wirgin
The problem, of 2D canonical nature, examined herein in the space-frequency framework, concerns a SH-polarized plane body seismic wave propagating in a hard, non lossy half space (…
Acoustic response of a rigid frame porous medium slab with a periodic set of inclusions
Jean-Philippe Groby, Armand Wirgin, Laurent De Ryck +1
The acoustic response of a rigid frame porous slab with a periodic set of inclusions is calculated by use of a multipole method. The acoustic properties, in particular the absorpti…
Seismic motion in urban sites consisting of blocks in welded contact with a soft layer overlying a hard half space: II. large and infinite number of identical equispaced blocks
Armand Wirgin, Jean-Philippe Groby
We address the problem of the response to a seismic wave of an urban site consisting of a large and infinite number () of identical, equispaced blocks overlying a soft laye…
Use of specific Green's functions for solving direct problems involving a heterogeneous rigid frame porous medium slab solicited by acoustic waves
Jean-Philippe Groby, Laurent De Ryck, Philippe Leclaire +4
A domain integral method employing a specific Green's function (i.e., incorporating some features of the global problem of wave propagation in an inhomogeneous medium) is developed…
