Multiscale Materials Modeling for Nanomechanics


Book Description

This book presents a unique combination of chapters that together provide a practical introduction to multiscale modeling applied to nanoscale materials mechanics. The goal of this book is to present a balanced treatment of both the theory of the methodology, as well as some practical aspects of conducting the simulations and models. The first half of the book covers some fundamental modeling and simulation techniques ranging from ab-inito methods to the continuum scale. Included in this set of methods are several different concurrent multiscale methods for bridging time and length scales applicable to mechanics at the nanoscale regime. The second half of the book presents a range of case studies from a varied selection of research groups focusing either on a the application of multiscale modeling to a specific nanomaterial, or novel analysis techniques aimed at exploring nanomechanics. Readers are also directed to helpful sites and other resources throughout the book where the simulation codes and methodologies discussed herein can be accessed. Emphasis on the practicality of the detailed techniques is especially felt in the latter half of the book, which is dedicated to specific examples to study nanomechanics and multiscale materials behavior. An instructive avenue for learning how to effectively apply these simulation tools to solve nanomechanics problems is to study previous endeavors. Therefore, each chapter is written by a unique team of experts who have used multiscale materials modeling to solve a practical nanomechanics problem. These chapters provide an extensive picture of the multiscale materials landscape from problem statement through the final results and outlook, providing readers with a roadmap for incorporating these techniques into their own research.

Nanotube Superfiber Materials


Book Description

Carbon nanotubes (CNTs) have been at the frontier of nanotechnology research for the past two decades. The interest in CNTs is due to their unique physical and chemical properties, which surpass those of most other materials. To put CNTs into macroscale applications, the nanotubes can be spun to form continuous fiber materials. Thus far, the properties of the fibers are far below the properties of the individual nanotubes. If the electrical and mechanical properties of the fibers could be improved, the resulting superfiber materials would change the industry and society. For example, CNT materials might replace copper wires providing lighter, stronger cables for aerospace applications. The small size of individual nanotubes, and the mixture of different diameters and chiralities, limits the electrical conductivity of CNT fiber. A simple way to improve the electrical conductivity of CNT fibers is chemically doping the CNTs within the fibers. This chapter attempts to summarize, classify and provide a basic understanding of doping at the atomic and molecular levels. Characterization of doping and current results of our doping efforts are discussed.
