Book Synopsis Elastic Wave Propagation by : F. McCarthy
Download or read book Elastic Wave Propagation written by F. McCarthy and published by Elsevier. This book was released on 2018-06-20 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a timely collection of research papers on the latest developments in the ever-increasing use of elastic waves in a variety of contexts. There are reports on wave-propagation in various types of media: in both isotropic and anisotropic bodies; in homogeneous and inhomogeneous media; in media with cracks or inclusions in random media; and in layered composites.The bulk of the papers are concerned with propagation in elastic media, but also included are viscoelastic, thermoelastic and magneto-electroelastic wave propagation, as well as waves in porous and piezo-electric bodies. Consideration is given to propagation in bodies as diverse as stretched elastic strings to surfaces such as thin walled cylinders, and thin films under stress. Applications considered include the determination of the depth of cracks; analysis of ground motions generated by a finite fault in seismology; surface wave spreading on piezo-electric solids; and dynamical stress intensity factors. Most of the papers are theoretical in nature, and many are complemented by numerical studies. Also included are a general survey on experimental techniques, and reports on experimental work.The volume will be of interest to those who do theoretical studies of elastic wave propagation and to those who apply elastic waves whether in seismology, non-destructive testing, the fabrication of devices or underwater acoustics, etc.

Download or read book Wavelets written by Jean-Michel Combes and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last two subjects mentioned in the title "Wavelets" are so well established that they do not need any explanations. The first is related to them, but a short introduction is appropriate since the concept of wavelets emerged fairly recently. Roughly speaking, a wavelet decomposition is an expansion of an arbitrary function into smooth localized contributions labeled by a scale and a position pa rameter. Many of the ideas and techniques related to such expansions have existed for a long time and are widely used in mathematical analysis, theoretical physics and engineering. However, the rate of progress increased significantly when it was realized that these ideas could give rise to straightforward calculational methods applicable to different fields. The interdisciplinary structure (R.c.P. "Ondelettes") of the C.N .R.S. and help from the Societe Nationale Elf-Aquitaine greatly fostered these developments. This conference was held at the Centre National de Rencontres Mathematiques (C.I.R.M) in Marseille from December 14 to 18, 1987 and brought together an interdisciplinary mix of participants. We hope that these proceedings will convey to the reader some of the excitement and flavor of the meeting.

This book was released on 2018-03-24 with total page 799 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of 2 special volumes dedicated to the memory of Gérard Maugin. Including 40 papers that reflect his vast field of scientific activity, the contributions discuss non-standard methods (generalized model) to demonstrate the wide range of subjects that were covered by this exceptional scientific leader. The topics range from micromechanical basics to engineering applications, focusing on new models and applications of well-known models to new problems. They include micro–macro aspects, computational endeavors, options for identifying constitutive equations, and old problems with incorrect or non-satisfying solutions based on the classical continua assumptions.
Book Synopsis Diffusion acoustique par des coques cylindriques limitées immergées by : Lionel Haumesser
Download or read book Diffusion acoustique par des coques cylindriques limitées immergées written by Lionel Haumesser and published by . This book was released on 2001 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: La pression acoustique diffusée par des tubes de longueur finie, immergés dans l'eau, est analysée expérimentalement et théoriquement dans les espaces de Fourier. La signature, spectrale et temporelle, de tels objets est interprétée en termes de résonance et de propagation d'ondes de surface. Les diffuseurs sont en acier inoxydable, de rapports des rayons interne sur externe égaux à 0,83 et 0,97. Ils sont excités en champ lointain par des signaux ultrasonores large bande, pour des angles d'incidence compris enter 0ʻ (incidence normale par rapport à l'axe principal des objets) et 50ʻ . Les résonances présentes dans les réponses spectrales rétro diffusées, relatives aux ondes hélicoïdales Sʻ et Tʻ, sont identifiées. Les modes de vibration associés sont déterminés expérimentalement en utilisant deux dispositifs de mesure bi-statiques. Un premier montage, où le transducteur récepteur tourne dans un plan perpendiculaire à l'axe du tube, conduit à l'identification des modes circonférentiels (n) ; un second montage original, où le récepteur se déplace parallèlement à l'axe de l'objet, permet d'identifier les modes axiaux (m). Ces résultats sont en accord avec ceux obtenus à l'aide d'une approche théorique modale hybride combinant la théorie de l'élasticité et l'intégrale de diffraction de Kirchhoff. Ces informations (fréquence de résonance, n, m) permettent d'évaluer la vitesse de phase et l'angle de propagation de l'onde correspondante. On réalise ainsi l'identification complète des résonances de l'objet (nature de l'onde, n, m). Chaque résonance, manifestation d'un mode propre de l'objet limité sélectionné par les conditions d'excitation, est observée à une seule fréquence pour plusieurs angles d'incidence voisins. Un modèle géométrique décrivant le parcours hélicoïdal des ondes sur le tube permet l'analyse des réponses temporelles. Les temps auxquels les échos sont observés, sont associés à des trajets de l'onde Tʻ. L'influence des dimensions des objets (longueur et diamètre) sur la rétro diffusion est ainsi étudiée. L'approche géométrique permet également de considérer les effets liés à la présence d'un disque radial dans les tubes : le rôle de l'onde A (onde d'interface) devient prédominant.
