Seismic Wave Propagation in Non-Homogeneous Elastic Media by Boundary Elements
Springer International Publishing (Verlag)
978-3-319-45205-0 (ISBN)
This book focuses on the mathematical potential and computational efficiency of the Boundary Element Method (BEM) for modeling seismic wave propagation in either continuous or discrete inhomogeneous elastic/viscoelastic, isotropic/anisotropic media containing multiple cavities, cracks, inclusions and surface topography. BEM models may take into account the entire seismic wave path from the seismic source through the geological deposits all the way up to the local site under consideration.
The general presentation of the theoretical basis of elastodynamics for inhomogeneous and heterogeneous continua in the first part is followed by the analytical derivation of fundamental solutions and Green's functions for the governing field equations by the usage of Fourier and Radon transforms. The numerical implementation of the BEM is for antiplane in the second part as well as for plane strain boundary value problems in the third part. Verification studies and parametric analysis appearthroughout the book, as do both recent references and seminal ones from the past.
Since the background of the authors is in solid mechanics and mathematical physics, the presented BEM formulations are valid for many areas such as civil engineering, geophysics, material science and all others concerning elastic wave propagation through inhomogeneous and heterogeneous media.
The material presented in this book is suitable for self-study. The book is written at a level suitable for advanced undergraduates or beginning graduate students in solid mechanics, computational mechanics and fracture mechanics.

"This book treats the theory of seismic waves by using various models of elastic media, and gives analytical and numerical solutions for problems with boundary conditions prescribed at two-dimensional domains, applying the boundary integral equation method (BIEM) AND Fourier-Laplace and Radon transforms. The book covers the state-of-the-art of the BIEM in the field of elastodynamics and can be considered a useful reading for researchers and graduate students in seismology."
