Описание: In 1978, the European Mechanics Committee and the French Centre National de la Recherche Scientifique agreed to the organization of an Interna- tional Colloquium on the "Mechanical Behavior of Anisotropic Solids". The meeting was held at Villard-de-Lans (near Grenoble, France) from 19th to 22 nd June 1979. The Colloquium considered mechanical aspects of the anisotropy of solids, both initial and induced by permanent deformation, anisotropic hardening and damage, oriented fissuration, etc. Topics concerned mathematical, experimental and engineering aspects of the anisotropy of metals, composites, soils and rocks. The aim of the Colloquium was to bring together experimentalists, theoretecians and engineers interested in various features of mechanical anisotropy, in order to permit an interdisciplinary exchange of understanding, experience and methods. A detailed description of the scope, aim and proposed topics is contained in the Preface. The announcement of the Colloquium attracted a large number of sub- mitted contributions. Conforming with the principles of Euromech Colloquia and of the Colloques Internationaux du CNRS, the accepted contributions were limited to 50 communications. A general description of the scientific program is to be found in the Preface. Five general lectures gave state-of-the-art reports concerning some areas of the behavior of anisotropic solids; the 50 communications were divided into 12 sessions dealing with specific topics (see "Contents"). In order to facilitate subsequent contact between the reader and the contributors, full addresses are given in the "List of Authors".

Описание: Structural geologists are well aware of the fact that isotropic rocks are quite exceptional in nature. Whicheverorigin, sedimentary, metamorphicormagmatic, rocks are shaped with a plane of mineral flattening, the foliation in geologists' jargon, and with a line ofmineral elongation, the lineation. Just like a good quarryman, a trained structural geologistwill detectapreferredorientationin an apparently isotropic granite. Preferred mineral orientation and thus structural anisotropy are the rule in nature. Consideringthe largevariationsinelasticcoefficientsofrock-forming minerals, itcould be predicted that, in turn, seismic anisotropy should exist and be important, provided thatdomains withasimilarstructural signatureare largeenough to affectseismic waves. This is why, in 1982 at a conference held in Frankfurt, which was oneofthe fIrst meetings devoted to the subject of seismic anisotropy, I asked Don Anderson the question of why seismologists had not considered earlier in their models the obvious constraint of anisotropy. I still remember Don's answer: "Adolphe, we knew that our isotropic models were not very good but we had no other choice. It is simply that, so far, computerswere not largeenough tointegrate the anisotropy parameter". Changingisotropic glassesfor anisotropic ones permits us to obtain betterand more realistic seismic modelsofthe Earth's interior, but, maybe more importantly, it has, for a seismologist, the farreaching consequenceofsteppinginto the fIeld ofgeodynamics.

Описание: Any undisturbed rock mass is subject to natural stresses inclu- ding gravitational stresses due to the mass of the overburden and possibly tectonic stresses due to the straining of the earth`s crust and remanent stresses due to past tectonism.

Описание:
This book presents two important new findings. First, it demonstrates from first principles that turbulent heating offers an explanation for the non-adiabatic decay of proton temperature in solar wind. Until now, this was only proved with reduced or phenomenological models. Second, the book demonstrates that the two types of anisotropy of turbulent fluctuations that are observed in solar wind at 1AU originate not only from two distinct classes of conditions near the Sun but also from the imbalance in Alfv?n wave populations. These anisotropies do not affect the overall turbulent heating if we take into account the relation observed in solar wind between anisotropy and Alfv?n wave imbalance.
In terms of the methods used to obtain these achievements, the author shows the need to find a very delicate balance between turbulent decay and expansion losses, so as to directly solve the magnetohydrodynamic equations, including the wind expansion effects.
Описание: The aim of this book is to extend and update the standard treatments of crystal optics found in classical textbooks. It provides a broad overview of electromagnetic anisotropy, bianisotropy, and chirality. The topics covered are constitutive relations (Chapter 1); examples of anisotropy, bianisotropy, and chirality (Chapter 2); spacetime symmetries (Chapter 3); planewave propagation (Chapter 4); dyadic Green functions including depolarization dyadics (Chapter 5); homogenization formalisms (Chapter 6); nonlinear aspects (Chapter 7); surface waves (Chapter 8) and topological insulators (Chapter 9). New additions in this second edition are: Chapters 8 and 9, expanded treatments of active mediums in Chapter 4, and the Huygens principle and the Ewald-Oseen extinction theorem in Chapter 5. This book is perfect for postbaccalaureate students and researchers seeking an introductory survey of the electromagnetic theory of complex mediums.
Описание: Wide-azimuth surveying has shown that most rocks are azimuthally anisotropic, with P-wave velocities and P-AVO gradients varying with azimuth. Analysis with narrow-azimuth algorithms and concepts will necessarily fail to exploit this data. This book shows how to recognise anisotropy effects in data and provides intuitive concepts to analyse it.

Описание:
This book focuses on the modeling, processing and visualization of anisotropy, irrespective of the context in which it emerges, using state-of-the-art mathematical tools. As such, it differs substantially from conventional reference works, which are centered on a particular application. It covers the following topics: (i) the geometric structure of tensors, (ii) statistical methods for tensor field processing, (iii) challenges in mapping neural connectivity and structural mechanics, (iv) processing of uncertainty, and (v) visualizing higher-order representations. In addition to original research contributions, it provides insightful reviews.
This multidisciplinary book is the sixth in a series that aims to foster scientific exchange between communities employing tensors and other higher-order representations of directionally dependent data. A significant number of the chapters were co-authored by the participants of the workshop titled Multidisciplinary Approaches to Multivalued Data: Modeling, Visualization, Analysis, which was held in Dagstuhl, Germany in April 2016.
It offers a valuable resource for those working in the field of multi-directional data, vital inspirations for the development of new models, and essential analysis and visualization techniques, thus furthering the state-of-the-art in studies involving anisotropy.
Описание: Contains 69 papers covering research in this field of solid mechanics. This work has grouped topics into eight sections: characterisation of anisotropic materials; large deformations and flow; numerical studies in plasticity; plasticity and granular materials; fracture and damage; anisotropic media; composite materials; and, waves and vibrations.

Описание: A Closer Look at Magnetic Anisotropy reports on results related to the impact of magnetic anisotropy on the properties of a new type of nanocomposite consisting of ferromagnetic nanoparticles embedded in carbon nanotubes. The authors demonstrate that when each nanotube contains only one ferromagnetic nanoparticle, the magneto-elastic anisotropy leads to the formation of densely packed arrays of magnetically isolated nanoparticles. Following this, the aspects of perpendicular magnetic anisotropy of FeCoZr-CaF2 nanocomposite films induced by shape anisotropy of metallic nanoparticles are explored, as well as the methods of anisotropy enhancement by the films treatment. Several examples of the prospective technical applications of magnetic liquids are presented. Three examples are discussed more in detail: controlled torsion dampers for applications in transportation, ferrofluid controlled capacitors for applications in sensor technology, and peristaltic pumps that take advantage of magneto-elastic properties.
