This book presents a set of basic understandings of the behavior and response of solids to propagating shock waves. The propagation of shock waves in a solid body is accompanied by large compressions, decompression, and shear. Thus, the shear strength of solids and any inelastic response due to shock­ wave propagation is of the utmost importance. Furthermore, shock compres­ sion of solids is always accompanied by heating, and the rise of local tempera­ ture which may be due to both compression and dissipation. For many solids, under a certain range of impact pressures, a two-wave structure arises such that the first wave, called the elastic prescursor, travels with the speed of sound; and the second wave, called a plastic shock wave, travels at a slower speed. Shock-wave loading of solids is normally accomplished by either projectile impact, such as produced by guns or by explosives. The shock heating and compression of solids covers a wide range of temperatures and densities. For example, the temperature may be as high as a few electron volts (1 eV = 11,500 K) for very strong shocks and the densification may be as high as four times the normal density.

Developments in experimental methods are providing an increasingly detailed understanding of shock compression phenomena on the bulk, intermediate, and molecular scales. This third volume in a series of reviews of the curent state of knowledge covers several diverse areas. The first group of chapters addresses fundamental physical and chemical aspects of the response of condensed matter to shock comression: equations of state, molecular-dynamic analysis, deformation of materials, spectroscopic methods. Two further chapters focus on a particular group of materials: ceramics. Another chapter discusses shock-induced reaction of condensed-phase explosives. And a final pair of chapters considers shock phenomena at low stresses from the point of view of continuum mechanics.

This volume concerns the fracture and fragmentation of solid materials that occurs when they are subjected to extremes of stress applied at the highest possible rates. The plan for the volume is to address experimental, theoretical, and com­ putational aspects of high-rate dynamic fracture and fragmentation, with emphasis on recent work. We begin with several chapters in which the emphasis falls on experimental methods and observations. These chapters address both macroscopic responses and the microscopic cause of these re­ sponses. This is followed by several chapters emphasizing modeling-the physical explanation and mathematical representation of the observations. Some of the models are deterministic, while others focus on the stochastic aspects of the observations. Often, the ov\!rall objective of investigation of dynamic fracture and fragmentation phenomena is provision of a means for predicting the entire course of an event that begins with a stimulus such as an impact and proceeds through a complicated deformation and fracture pro­ cess that results in disintegration of the body and formation of a rapidly expanding cloud of debris fragments. Analysis of this event usually involves development of a continuum theory and computer code that captures the experimental observations by incorporating models of the important pheno­ mena into a comprehensive description of the deformation and fracture pro­ cess. It is to this task that the work of the last few chapters is devoted.

Smart materials are of significant interest and this is the first textbook to provide a comprehensive graduate level view of topics that relate to this field. Fundamentals of Smart Materials consists of a workbook and solutions manual covering the basics of different functional material systems aimed at advanced undergraduate and postgraduate students. Topics include piezoelectric materials, magnetostrictive materials, shape memory alloys, mechanochromic materials, thermochromic materials, chemomechanical polymers and self-healing materials. Each chapter provides an introduction to the material, its applications and uses with example problems, fabrication and manufacturing techniques, conclusions, homework problems and a bibliography. Edited by a leading researcher in smart materials, the textbook can be adopted by teachers in materials science and engineering, chemistry, physics and chemical engineering.

Ionic polymer metal composites (IPMCs) can generate a voltage when physically deformed. Conversely, an applied small voltage or electrical field can induce an array of spectacular large deformation or actuation behaviours in IPMCs, such as bending, twisting, rolling, twirling, steering and undulating. An important smart material, IPMCs have applications in energy harvesting and as self-powered strain or deformation sensors, especially suitable for monitoring the shape of dynamic structures. Other uses include soft actuation applications and as a material for biomimetic robotic soft artificial muscles in industrial and medical contexts. This comprehensive set on ionic polymer metal composites provides a broad coverage of the state of the art and recent advances in the field written by some of the world’s leading experts on various characterizations and modeling of IPMCs. The first two chapters cover the fundamentals of IPMCs and methodologies for their manufacture, followed by specific chapters looking at different aspects of actuation and sensing of IPMCs. These include uses in electrochemically active electrodes, electric energy storage devices, soft biomimetic robotics artificial muscles, multiphysics modeling of IPMCs, biomedical applications, IPMCs as dexterous manipulators and tactile sensors for minimally invasive robotic surgery, self-sensing, miniature pumps for drug delivery, IPMC snake-like robots, IPMC microgrippers for microorganisms manipulations, Graphene-based IPMCs and cellulose-based IPMCs or electroactive paper actuators (EAPap). Edited by the leading authority on IMPCs, the broad coverage of this book will appeal to researchers from chemistry, materials, engineering, physics and medical communities interested in both the material and its applications.

Robotic surgery has already created a paradigm shift in medical surgical procedures and will continue to expand to all surgical and microsurgical interventions. There is no doubt that in doing so robotic surgical systems, such as the da Vinci surgical system, will become smarter and more sophisticated with the integration, implementation, and synergy of new smart multifunctional material systems that will make surgical tools and equipment more functional in biomimetic sensing and actuation incorporating haptic/tactile feedback to surgeons in connection with kinesthetic interaction with organs during robotic surgery. This book is the first textbook in robotic surgery to discuss the integration of smart multifunctional soft and biomimetic materials with robotic end effectors to provide haptic and tactile feedback to surgeons during robotic surgery. It is also the first textbook in robotic surgery that comes with a solutions manual, which makes it useful as a supplement to faculty members teaching many different programs and courses such as robotics, medical devices, surgical interventions, and many more.This book can be adapted by professors to teach graduate students and researchers, to enable them to further employ their creativity and knowledge, and to undergraduates to enable them to get an excellent grasp of this exciting field. It is also useful for individuals interested in the field for self-study. The background required for this book is college-level mathematics, matrix analysis, geometry, and medical/surgical terminologies.
