Abstract
In this work, we develop Green's functions for SH waves in an elastic continuum
exhibiting large randomness. These functions are subsequently used within the
context of BEM formulations for wave scattering problems of engineering
interest. More specifically, the methodology developed here employs a series
expansion for the proposed Green's functions, where the basis functions are
orthogonal polynomials of a random argument. The corresponding BEM
formulation is then done in the Fourier transform domain. This way, we depart
from earlier BEM derivations based on perturbations, which imply the presence
of "small" amounts of randomness in the elastic continuum.
