The Second International Symposium on Constitutive Modeling of Geomaterials: Advances and New Applications (IS-Model 2012), is to be held in Beijing, China, during October 15-16, 2012. The symposium is organized by Tsinghua University, the International Association for Computer Methods and Advances in Geomechanics (IACMAG), the Committee of Numerical and Physical Modeling of Rock Mass, Chinese Society for Rock Mechanics and Engineering, and the Committee of Constitutive Relations and Strength Theory, China Institution of Soil Mechanics and Geotechnical Engineering, China Civil Engineering Society. This Symposium follows the first successful International Workshop on Constitutive Modeling held in Hong Kong, which was organized by Prof. JH Yin in 2007. Constitutive modeling of geomaterials has been an active research area for a long period of time. Different approaches have been used in the development of various constitutive models. A number of models have been implemented in the numerical analyses of geotechnical structures. The objective of the symposium is to provide a forum for researchers and engineers working or interested in the area of constitutive modeling to meet together and share new ideas, achievements and experiences through presentations and discussions. Emphasis is placed on recent advances of constitutive modeling and its applications in both theoretic and experimental aspects. Six famous scholars have been invited for the plenary speeches of the symposiums. Some prominent scholars have been invited to organize four specialized workshops on hot topics, including “Time-dependent stress-strain behavior of geomaterials”, “Constitutive modeling within critical state soil mechanics”, “Multiscale and multiphysics in geomaterials”, and “Damage to failure in rock structures”. A total of 49 papers are included in the above topics. In addition, 51 papers are grouped under three topics covering “Behaviour of geomaterials”, “Constitutive model”, and “Applications”. The editors expect that the book can be helpful as a reference to all those in the field of constitutive modeling of geomaterials.

Adiabatic shear localization is a mode of failure that occurs in dynamic loading. It is characterized by thermal softening occurring over a very narrow region of a material and is usually a precursor to ductile fracture and catastrophic failure. This reference source is the revised and updated version of the first detailed study of the mechanics and modes of adiabatic shear localization in solids. Building on the success of the first edition, the book provides a systematic description of a number of aspects of adiabatic shear banding. The concepts and techniques described in this work can usefully be applied to solve a multitude of problems encountered by those investigating fracture and damage in materials, impact dynamics, metal working and other areas. Specific chapters focus on energetic materials, polymers, bulk metal glasses, and the mathematics of shear banding as well as the numerical modeling of them. With its detailed coverage of the subject, this book is of great interest to academics and researchers into materials performance as well as professionals. Up-to-date coverage of the subject and research that has occurred over the past 20 years Each chapter is written on a different sub-field of adiabatic shear by an acknowledged expert in the field Detailed and clear discussions of each aspect

When the Apollo 11 astronauts landed on the Moon on July 20, 1969, they made a very important discovery. During their landing on the surface of the Moon, the exhaust gases released from the Lunar Module landing rockets caused large amounts of surface dust to move into the thin lunar atmosphere, causing obscuration of the lunar surface. Once they landed, they found that the surface of the Moon was covered with several inches of very fine, tiny particles composed of sharp, glassy material. The lunar dust stuck to everything it came in contact with, and, once on the lunar surface, the dust eroded their spacesuits, caused overheating on equipment and instrumentation, compromised seals on their spacesuits and on lunar sample collecting boxes, irritated their eyes and lungs, and generally coated everything very efficiently. On the return to Earth in the Apollo Command Module, lunar dust inadvertently brought aboard floated freely in their cabin causing problems. Now, 50 years later, humans will return to the Moon in the Artemis Program, as early as 2024. This book summarizes what we know about lunar dust, its structure and chemical composition, its impact on human health, and how to reduce/mitigate its effects on future human exploration. The four dozen contributors to the 14 chapters in the book are planetary scientists, engineers, mission planners, medical researchers and physicians from NASA and the European Space Agency (ESA), as well as universities and industry from the United States, Australia, Germany, Italy, the Netherlands, Portugal and Sweden.

Soft condensed matter is a relatively new topic. Condensed matter has typically referred to more traditional liquids, which have a long history of study, or to solids, which have focused more commonly on hard materials, driven in large measure by the importance of structural materials or the metals and semiconductors which drove the rapid evolution of microelectronics. It is only relatively recently, over the past 20 to 30 years, that soft condensed matter has matured into its own identifiable field. However, the field is an amalgam of many subfields, and many of these have themselves much longer histories. This handbook serves as an overview of many of these topics. Because of the great breadth, it is impossible to include them all; nevertheless, the key subjects of soft condensed matter are represented here. Together, they form both an introduction and an overview of the field. Each topic, and its representing Chapter, could have been a full size book - in fact, there are a number of such books on many of the topics covered in the handbook. Our aim here was to give a current snapshot of the field, identify the key principles at play and the most prominent (and promising) ways of its further development, provide essential references for anyone to follow the subject, but not necessarily go into a lot of detail on each topic.

In this contribution the novel system for the dynamic flowsheet simulation of solids processes is presented. The system is generally applicable for all types of solids processes without limitation for specific process types. In a distinction to the existing flowsheet simulation systems, which have been mainly developed with a focus on fluid processes, the novel system allows to treat multidimensional distributed parameters properly. To perform dynamic modeling of various industrial plants the library of dynamic units has been developed. These units can be easily added per drag and drop functionality onto the flowsheet and in this way the necessary process structure can be created. To make a simulation of various granulation plants the new dynamic models of fluidized bed spray granulation have been developed and implemented. The fluidized bed spray granulation is widely used in the chemical, pharmaceutical, food and agricultural industries. In the majority of cases the granulation plants have a complex dynamic or even unstable behavior. Therefore, the dynamic simulation is one the of most effective way to understand process transient behavior, to optimize process and to develop different control strategies. However, for the flowsheet simulation primarily empirical or semi-empirical models are used, where material microparameters and specific apparatus properties are poorly considered. To obtain more detailed estimation of process behavior, the multiscale modeling concept of solids processes has been developed. On the basis of the multiscale modeling methodology the novel multiscale simulation environment has been created. This environment consists of several models, which describe the process on different time and length scales, and has been effectively applied to the fluidized bed spray granulation process.

Chemical engineering applications have been a source of challenging optimization problems in terms of economics and technology. The goal of this book is to enable the reader to get instant information on fundamentals and advancements in chemical engineering. This book addresses ongoing evolutions of chemical engineering and provides overview to the sate of the art advancements. Molecular perspective is increasingly important in the refinement of kinetic and thermodynamic molding. As a result, much of the material was revised on industrial problems and their sophisticated solutions from known scientists around the world. These issues were divided in to two sections, fundamental advances and catalysis and reaction engineering. A distinct feature of this text continues to be the emphasis on molecular chemistry, reaction engineering and modeling to achieve rational and robust industrial design. Our perspective is that this background must be made available to undergraduate, graduate and professionals in an integrated manner.

This book focuses on the impact dynamics and cratering of soft matter to describe its importance, difficulty, and wide applicability to planetary-related problems. A comprehensive introduction to the dimensional analysis and constitutive laws that are necessary to discuss impact mechanics and cratering is first provided. Then, particular coverage is given to the impact of granular matter, which is one of the most crucial constituents for geophysics. While granular matter shows both solid-like and fluid-like behaviors, neither solid nor fluid dynamics is sufficient to fully understand the physics of granular matter. In order to reveal its fundamental properties, extensive impact tests have been carried out recently. The author reveals the findings of these recent studies as well as what remains unsolved in terms of impact dynamics. Impact crater morphology with various soft matter impacts also is discussed intensively. Various experimental and observational results up to the recent Itokawa asteroid’s terrain and nanocrater are reviewed and explained mainly by dimensional analysis. The author discusses perspectives of the relation between soft matter physics and planetary science, because it is an important step towards unifying physics and planetary science, in both of which fields crater morphology has been studied independently.
