Public ISBD Titre : Finit-element modelling of unbounded media Type de document : texte imprimé Auteurs : John P. Wolf, Auteur ; Song , Chongmin Editeur : New York : John Wiley & Sons Année de publication : 1996 Importance : X-331 p. Présentation : ill. Format : 25 cm ISBN/ISSN/EAN : 978-0-471-96134-5 Note générale : Bibliogra.p.319-324.-Index Langues : Anglais (eng) Mots-clés : Structures Index. décimale : 624.041.2 Structures statiquement indéterminées en général Résumé : This book presents three novel concepts, basedon the finite-element methodology, to model the unboundedmedium: The consistent infinitesimal finite-element cell method, aboundary finite-element procedure, requires the discretization ofthe structure-medium interface only and is exact in thefinite-element sense. It is applied to unbounded media governed bythe hyperbolic, parabolic and elliptic differentialequations. The damping-solvent extraction method permits the analysis of abounded medium only. The doubly-asymptotic multi-directional transmitting boundary isexact for the low- and high-frequency limits at preselected wavepropagation directions. All concepts are explained using simple examples that the readercan follow step by step. A computer program of the consistentinfinitesimal finite-element cell method available on disk analysestwo- and three-dimensional unbounded and bounded media for thescalar and vector wave equations and the diffusion equation in thefrequency and time domains.
