In particular, a derivation of absorbing boundary conditions in viscoelastic and poroelastic media is presented, which later is employed in the applications. \u003cp\u003e\u003c\/p\u003eThe partial differential equations describing the propagation of waves in Biot media are solved using the Finite Element Method (FEM). \u003cp\u003e\u003c\/p\u003eWaves propagating in a Biot medium suffer attenuation and dispersion effects. In particular the fast compressional and shear waves are converted to slow diffusion-type waves at mesoscopic-scale heterogeneities (on the order of centimeters), effect usually occurring in the seismic range of frequencies. \u003cp\u003e\u003c\/p\u003eIn some cases, a Biot medium presents a dense set of fractures oriented in preference directions. When the average distance between fractures is much smaller than the wavelengths of the travelling fast compressional and shear waves, the medium behaves as an effective viscoelastic and anisotropic medium at the macroscale. \u003cp\u003e\u003c\/p\u003eThe book presents a procedure determine the coefficients of the effective medium employing a collection of time-harmonic compressibility and shear experiments, in the context of Numerical Rock Physics. Each experiment is associated with a boundary value problem, that is solved using the FEM. \u003cp\u003e\u003c\/p\u003eThis approach offers an alternative to laboratory observations with the advantages that they are inexpensive, repeatable and essentially free from experimental errors. \u003cp\u003e\u003c\/p\u003eThe different topics are followed by illustrative examples of application in Geophysical Exploration. In particular, the effects caused by mesoscopic-scale heterogeneities or the presence of aligned fractures are taking into account in the seismic wave propagation models at the macroscale. \u003cp\u003e\u003c\/p\u003eThe numerical simulations of wave propagation are presented withsufficient detail as to be easily implemented assuming the knowledge of scientific programming techniques.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Juan Enrique Santos,Patricia Mercedes Gauzellino\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3319484567\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783319484563\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Birkhauser\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 01\/14\/2017\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 309\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.01lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 0.69d","brand":"Juan Enrique Santos","offers":[{"title":"Paperback","offer_id":48089089442047,"sku":"9783319484563","price":84.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_4ea5ef63-caca-431b-89b5-ba43dd7bf522.jpg?v=1769108135","url":"https:\/\/www.whiterainbookhouse.com\/products\/numerical-simulation-in-applied-geophysics-juan-enrique-santos-9783319484563","provider":"WR Book House","version":"1.0","type":"link"}
