Granular systems arise in a variety of geological and industrial settings, from landslides, avalanches, and erosion to agricultural grains and pharmaceutical powders. Understanding the underlying physics that governs their behavior is the key to developing effective handling and transport mechanisms as well as appropriate environmental policies.

Handbook of Granular Materials presents foundational techniques used to investigate granular systems, examples of their use in contemporary research, and extensions to granular-like systems that greatly expand the realm of...

Applied Engineering Failure Analysis: Theory and Practice provides a point of reference for engineering failure analysis (EFA) cases, presenting a compilation of case studies covering a 35-year period, from the 1970s to 2012. This period spans the era from the time when slide rules were used routinely for engineering calculations, and when hard-copy photographs taken by film cameras were pasted onto typewritten sheets to make reports, to the present time when all these functions have become much less onerous through computer assistance.

The cases are drawn from...

This book - a sequel of previous publications 'Flows and Chemical Reactions' and 'Chemical Reactions in Flows and Homogeneous Mixtures' - is devoted to flows with chemical reactions in heterogeneous environments. Heterogeneous media in this volume include interfaces and lines. They may be the site of radiation. Each type of flow is the subject of a chapter in this volume.

We consider first, in Chapter 1, the question of the generation of environments biphasic individuals: dusty gas, mist, bubble flow. Chapter 2 is devoted to the study at the mesoscopic scale: particle-fluid exchange...

This book - a sequel of previous publications 'Flows and Chemical Reactions', 'Chemical Reactions Flows in Homogeneous Mixtures' and 'Chemical Reactions and Flows in Heterogeneous Mixtures' - is devoted to flows with chemical reactions in the electromagnetic field.

The first part, entitled basic equations, consists of four chapters. The first chapter provides an overview of the equations of electromagnetism in Minkowski spacetime. This presentation is extended to balance equations, first in homogeneous media unpolarized in the second chapter and homogeneous fluid medium polarized in...

The Second International Interdisciplinary Conference on Stress and Tension Control, sponsored by the International Stress and Tension Control Society, was held at The University of Sussex, Brighton, England during the period August 30 - September 3, 1983. The Society has evolved from the American Association for the Advancem t of Tension-Control, which met each year for five years in Chicago commen cing in 1974, and for which proceedings such as these were published annually. Because of an international flavor which the association gradually acquired the name was changed to that of The...

Turbulence takes place in most flow situations whethertheyoccur naturally or in technological systems. Therefore, considerable effort is being expended in an attempt to understand the phenomenon of turbulence. The recent discovery ofcoherent structure in turbulent shear flows and the modem developments in computer capabilities have revolutionized research work in turbulence. There is a strong evidence that the coherent structure in turbulent shear flows is reminiscent of nonlinear stability waves. As such, the interest in nonlinear stability waves has increased not only for the...

Biomembranes are not only principal constituents of the cell but also a major site of biological activity. Studies on biomembranes are therefore, crucial for furthering our understanding of life processes. A special research project on biomembranes involving more than 100 in- vestigators was conducted under a grant from the Ministry of Education, Science and Culture of Japan between 1978 and 1981. This has resulted in marked progress on basic biomedical studies on biomembranes in Japan. This book is a compilation of several major developments made during this project in the field of...

The papers comprising this collection are directly or indirectly related to an important branch of mathematical physics - the mathematical theory of wave propagation and diffraction. The paper by V. M. Babich is concerned with the application of the parabolic-equation method (of Academician V. A. Fok and M. A, Leontovich) to the problem of the asymptotic behavior of eigenfunc- tions concentrated in a neighborhood of a closed geodesie in a Riemannian space. The techniques used in this paper have been found useful in solving certain problems in the theory of open resonators. The topic of G. P....

Stromt Luft mit maBiger Geschwindigkeit, so sind die in der Stromung auftretenden Druckunterschiede gegenuber dem Atmospharendruck der artig gering, daB man, von Spezialfallen abgesehen, die resultierende Dichte-, Temperatur-und Volumenanderung des stromenden Mediums bei theoretischen Untersuchungen vernachlassigen darf. Die nicht zu schnell stromende Luft wird deshalb als inkompressibel, d. h. als unzu sammendruckbar betrachtet. Dies ermoglicht die Gesetze der Aero dynamik auf diejenigen der Hydrodynamik zuruckzufiihren. Da jedoch die Druckunterschiede etwa im Quadrat der...

In this introductory text, physics concepts are introduced as a means of understanding experimental observations, not as a sequential list of facts to be memorized. The book is structured around the key scientific discoveries that led to much of our current understanding of the universe. Numerous exercises are provided that utilize Mathematica software to help students explore how the language of mathematics is used to describe physical phenomena. Topics requiring quantum mechanics for a more complete explanation are identified but not pursued. In a departure from the traditional methodology...

In 1991, my newly formed researchgroupat Berkeley was working intensely in the area of continuum-level constitutive relationships that could be obtained in a deductive mannerfrom microstructuralinformationthroughthemethods of homogenization theory. Of particular interest was the application of such methods to structural problems in the blossoming field of micromechanical devices. In this context it was becoming evident that we needed to learn to navigate through the continuum/discrete interface. Such were the circumstances when Vladimir Granik came to visit us at Berkeley for the first time....

5 The symposium was held in Freudenstadt from 28h to 31 ofAugust st nd 1967 and in Stuttgart from 1 to 2 of September 1967. The proposal to hold this symposium originated with the German Society of Applied Mathematics and Mechanics (GAMM) late in 1964 and was examined by a committee of IUTAM especially appointed for this purpose. The basis of this examination was a report in which the present situation in the field and the possible aims of the symposium were surveyed. Briefly, the aims of the symposium were stated to be 1. the unification of the various approaches developed in recent years...
