Beschreibung

Nanotechnology is a progressive research and development topic withlarge amounts of venture capital and government funding beinginvested worldwide. Nano mechanics, in particular, is the study andcharacterization of the mechanical behaviour of individual atoms,systems and structures in response to various types of forces andloading conditions. This text, written by respected researchers in the field,informs researchers and practitioners about the fundamentalconcepts in nano mechanics and materials, focusing on theirmodelling via multiple scale methods and techniques. The booksystematically covers the theory behind multi-particle andnanoscale systems, introduces multiple scale methods, and finallylooks at contemporary applications in nano-structured andbio-inspired materials.

Klappentext
The ability to synthesize and analyse the properties of nanoscale objects has revolutionized a wide range of advanced biomedical, mechanical, electrical, smart material and military engineering applications. Nano mechanics, the study and characterization of the mechanical behaviour of individual atoms, systems and structures in response to various loading conditions, has fuelled this progressive technology. In particular, multiple scale modelling methods have allowed engineers to gain a better understanding of nano materials. Written by respected researchers in the field, this book examines the fundamental concepts in nano mechanics and materials, focusing on their modelling via multiple scale methods and techniques. Nano Mechanics and Materials: Theory, Multiscale Methods and Applications also provides:
* information on the foundations of molecular forces, particle systems and lattice mechanics; * the theory, formulae and implementation of current multiple scale modelling techniques; * analysis of mechanical, biological, self-healing and nano/bio composite materials and systems; * a supplementary website containing accompanying PowerPoint lecture notes. A comprehensive tutorial on the subject for practising electronics engineers, materials scientists and researchers developing nanoscale materials and applications, this text is also an up-to-date reference for graduates taking courses on nano mechanics or nanotechnology.
