Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage propose une méthode de construction de schémas numériques de grande précision sur la base d'une analyse spectrale de l'erreur. Ces schémas sont appliqués à la propagation des ondes mais ils peuvent l'être à la résolution par différences finies de tout autre système d'équations aux dérivées partielles. Plusieurs formulations du problème continu sont exposées mais on retient la formulation en vitesses de déplacement et en contraintes. D'autre part, une analyse des caractéristiques des équations de la propagation conduit à faire une comparaison avec les caractéristiques des équations de la mécanique des fluides et d'indiquer les conditions de la filiation. La discrétisation des équations est basée sur les schémas en grilles décalées. On effectue des développements de Taylor à des ordres élevés et une analyse de l'erreur de discrétisation par transformée de Fourier. Puis, on introduit la notion d'approximation optimale en contraste avec les approximations basées sur l'erreur de troncature. Les schémas construits restent de type convolutif. Le calcul s'avère très efficace sur la base de l'erreur relative de discrétisation. L'algorithme de calcul des coefficients d'approximation optimale est fourni en Fortran dans une annexe. L'élévation de l'ordre en temps consiste à reporter le calcul des dérivées d'ordre élevé en temps sur des dérivées d'ordre élevé en espace. Enfin, l'analyse des conditions de stabilité et de dispersion est réalisée pour prendre en compte l'approximation optimale des dérivées pour des ordres élevés en espace et en temps.

Download or read book Sonar and Underwater Acoustics written by Jean-Paul Marage and published by John Wiley & Sons. This book was released on 2013-02-07 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sonar and Underwater Acoustics brings together all the concepts necessary for designers and users of sonar systems. Unlike other books on this subject, which are often too specialized, this book is accessible to a wider audience. The first part focuses on the acoustic environment, antenna structures, and electric acoustic interface. The latter provides knowledge required to design, as well as the development and implementation of chain processes for an active sonar from the conditioning input to output processing. The reader will find a comprehensive range of all problems encountered in underwater acoustics for a sonar application, from physical phenomena governing the environment and the corresponding constraints, through to the technical definition of transducers and antennas, and the types of signal processing involved. In one section, measures in underwater acoustics are also proposed.

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 Nonlinear Waves in Elastic Crystals written by Gérard A. Maugin and published by . This book was released on 1999 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mathematical modelling of changing structures in materials is of increasing importance to industry where applications of the theory are found in subjects as diverse as aerospace and medicine. This book deals with aspects of the nonlinear dynamics of deformable ordered solids (known as elastic crystals) where the nonlinear effects combine or compete with each other. Physical and mathematical models are discused and computational aspects are also included. Different models are considered - on discrete as well as continuum scales - applying heat, electricity, or magnetism to the crystal structure and these are analysed using the equations of rational mechanics. Students are introduced to the important equations of nonlinear science that describe shock waves, solitons and chaos and also the non-exactly integrable systems or partial differential equations. A large number of problems and examples are included, many taken from recent research and involving both one-dimensional and two-dimensional problems as well as some coupled degress of freedom.
Download or read book Group 15 Mechanics of Fluids written by A. T. Troskolański and published by Elsevier. This book was released on 2014-05-12 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vocabulary of Mechanics, Volume 2: Group 15. Mechanics of Fluids provides information pertinent to the fundamental aspects of the mechanics of fluids. This book covers a variety of topics, including fluid mechanics, hydrostatics, aeromechanics, gas dynamics, aeroelasticity, and dynamic meteorology. Organized into two parts encompassing 95 sections, this volume begins with an overview of the branch of mechanics dealing with the phenomena of fluids in motion and at rest. This text then deals with the geometrical description of the flow of matter, irrespectively of the forces producing the motion. Other sections consider the instantaneous motion of a fluid element wherein the motion is composed of translation of the center of mass of a fluid element. This book discusses as well the relative equilibrium of liquids. The final section deals with the atmospheric air motion caused by several factors. This book is a valuable resource for engineers, scientists, and research workers.
