A large part of the research currently being conducted in the fields of materials science and engineering mechanics is devoted to carbon nanotubes and their applications. In this process, modeling is a very attractive investigation tool due to the difficulties in manufacturing and testing of nanomaterials. Continuum modeling offers significant advantages over atomistic modeling. Furthermore, the lack of accuracy in continuum methods can be overtaken by incorporating input data either from experiments or atomistic methods. This book reviews the recent progress in continuum modeling of carbon nanotubes and their composites. The advantages and disadvantages of continuum methods over atomistic methods are comprehensively discussed. Numerical models, mainly based on the finite element method, as well as analytical models are presented in a comparative way starting from the simulation of isolated pristine and defected nanotubes and proceeding to nanotube-based composites. The ability of continuum methods to bridge different scales is emphasized. Recommendations for future research are given by focusing on what still continuum methods have to learn from the nano-scale. The scope of the book is to provide current knowledge aiming to support researchers entering the scientific area of carbon nanotubes to choose the appropriate modeling tool for accomplishing their study and place their efforts to further improve continuum methods.

Carbon nanotubes are macromolecules of carbon in a periodic hexagonal arrangement with a cylindrical shell shape. Carbon nanotubes have been subjected to extensive research, with subsequent predictions of extremely high strength and exceptional electronic and thermal properties. They also hold substantial promise as fibers in composites and other devices for the development of superconductive devices for micro-electro-mechanical and nano-electro-mechanical system applications. It is expected that the material has great potential in biological, medical, energy storage, sensor, and other applications. It has been broadly recognized that atomic modeling of carbon nanotube is a powerful tool for analysis of carbon nanotube. Due to massive computations involved, the atomic modeling is limited to systems with a small number of molecules and atoms. On the other hand, attempts at applying continuum mechanics models to better investigate the analysis of carbon nanotube with large sizes have been initiated. However, continuum models are unable to adequately capture the atomic structures of carbon nanotube, and the applicability of the models needs to be justified. Recently, developments of multiscale methods have been proposed to the analysis of carbon nanotube. This book is dedicated to the publication of recent developments in modeling of carbon nanotube via atomic modeling, continuum modeling and multiscale methods for predictions of mechanical, electronic, and thermal properties of carbon nanotube. A wide range of fundamentally theoretical, computational topics on modeling and applications of carbon nanotube will be covered in the book. In addition, applications of carbon nanotubes as nano-devices in atomic and molecular transportations and bistable devices in switching or memory elements in signal processing and communications are also reported. It is with great pleasure that we present this book that covers a very wide and varied range of subject areas in modeling and applications of carbon nanotubes. The first chapter employs molecular dynamics simulations to show macroscopic flows of atomic and molecular hydrogen, helium, and a mixture of both gases both inside and outside a carbon nanotube. In particular, the simulations show a nanoseparation effect of the two gases. The new results in the chapter show the mass selectivity of the nanopumping effect can be used to develop a highly selective filter for various gases. The second chapter introduces a fine continuum model that is developed by virtue of the higher-order continuum theory. Moreover, a mesh-free computational framework is developed to implement the numerical simulation of single- walled carbon nanotubes. The rationality of the higher-order continuum model and the efficiency of mesh-free method are illustrated and discussed in the chapter. The study on the mechanics of buckled single-walled and multiwalled carbon nanotubes, carbon nanotube bundles and coupling effect between adjacent carbon nanotubes is reported in chapter three. Simple expressions of the buckle wavelength, amplitude and critical strain for buckling are given analytically, which show good agreement with experiments. Chapter 4 investigate the applicability of elastic shell model in analysis of graphene and carbon nanotubes. The author reports that the elasticity of graphene should be modeled as a shell composed of 2-dimensional (2D) isotropic materials with proper parameters rather than conventional 3D materials based on calculations by density functional theory. In addition, the elasticity of single-walled carbon nanotube with relative large radius can also be modeled as a shell composed of 2D isotropic materials, whereas the elasticity of single-walled carbon nanotubes with relative small radius should be modeled as a more complicated shell with seven elastic constants rather than the orthotropic thin shell. Mechanical integrity of carbon nanotubes is summarized in chapter 5. Young s modulus for the resistance to the infinitesimal deformation and ultimate strength to the finite deformation are tabled, which have been obtained by experiments, molecular dynamics simulations, and ab-initio calculations. Also the recent continuous modeling of carbon nanotubes is sorted out in tracing its advancement in the chapter. Chapter 6 presents an overview of studies on the wave propagation and the vibrational properties in carbon nanotubes by computational modeling and simulation. The models include the atomic-based continuum model, the Euler-beam model, the Timoshenko beam model, and the three-dimensional elastic shell model. Chapter seven reports the investigations of torsional buckling of both single-walled and double-walled carbon nanotubes. In the study of doubled-walled carbon nanotubes via molecular dynamics, a newly revealed buckling mode with one or three thin local rims on the outer tube is discovered while the inner tube shows a helically aligned buckling mode in three dimensions. The distinct buckling modes of the two tubes imply the inapplicability of continuum mechanics modeling in which it is postulated that the buckling modes of the constituent tubes have the same shape. The mechanical properties of single walled carbon nanotubes under both tensile and torsion are investigated using classical molecular dynamics simulations in chapter 8, based on reactive empirical bond-order potential. Based on the predicted mechanical properties, it is predicted that nanotubes may represent new candidates for novel porous, flexible and high strength and tough materials, e.g. ideal as scaffolds in the regenerative medicine. Bistable devices have been widely used as switching or memory elements in signal processing and communications. The bistablity is generally realized electrically or optically. Due to their small size and unique mechanical properties, carbon nanotubes have been proposed to form bistable devices mechanically. The chapter 9 reviews the recent advances of mechanical bistable devices of carbon nanotubes. In the final chapter, the authors have discussed a theoretical model based on kinetic concept of fracture of solids and molecular mechanics simulations for studying the time-dependent behavior of single-walled carbon nanotubes. The major advantage of this model is that the problem of real-time molecular level simulation is circumvented. Compared with recently published data on creep rupture of SWCNT ropes, it is seen that the predictions by the present model is quite reasonable, thus setting up a framework for modeling the time-dependent behavior of carbon nanotubes and their composites. We would like to extend our sincere thanks to the authors for their contributions, especially their precious time and efforts invested in the book. We also would like to thank Transworld Research Network Publishers for the opportunity to publish the book to address very important and challenging issues. The support and love from our families are deeply appreciated.

This discovery of carbon nanotubes (CNT) three decades ago ushered in the technological era of nanotechnology. Among the most widely studied areas of CNT research is their use as structural reinforcements in composites. This book describes the development of CNT reinforced metal matrix composites (CNT-MMCs) over the last two decades. The field of CNT-MMCs is abundant in fundamental science, rich in engineering challenges and innovations and ripe for technological maturation and commercialization. The authors have sought to present the current state of the-art in CNT-MMC technology from their synthesis to their myriad potential end-use applications. Specifically, topics explored include: • Advantages, limitations, and evolution of processing techniques used to synthesize and fabricate CNT-MMCs • Emphasizes dispersion techniques of CNTs in metallic systems, a key challenge to the successful and widespread implementation of CNT-MMCs. Methods for quantification and improved control of CNT distributions are presented • Methods for quantification and improved control of CNT distributions are presented • Characterization techniques uniquely suited for charactering these nanoscale materials and their many chemical and physical interactions with the metal matrix, including real-time in-situ characterization of deformation mechanisms • Electron microscope images from premier studies enrich discussions on micro-mechanical modeling, interfacial design, mechanical behavior, and functional properties • A chapter is dedicated to the emergence of dual reinforcement composites that seek to enhance the efficacy of CNTs and lead to material properties by design This book highlights seminal findings in CNT-MMC research and includes several tables listing processing methods, associated CNT states, and resulting properties in order to aid the next generation of researchers in advancing the science and engineering of CNT-MMCs. In addition, a survey of the patent literature is presented in order to shed light on what the first wave of CNT-MMC commercialization may look like and the challenges that will have to be overcome, both technologically and commercially.
