Kurzbeschreibung
Written by respected researchers in the field, Nano Mechanics and Materials informs researchers and practitioners about the fundamental concepts in nano mechanics and materials, focusing on their modeling via multiple scale methods and techniques. The book systematically covers the theory behind multi-particle and nanoscale systems, introduces multiple scale methods, and finally looks at contemporary applications in nano-structured and bio-inspired materials. The authors begin by explaining the potential of nanoscale engineering, and the rationale behind the multiple scale modeling method in a comprehensive introduction. They then follow this by providing theoretical information on the mechanics of a system of particles, molecular forces, and lattice mechanics. The next chapter introduces the reader to potential methods used to analyze these materials, which most importantly includes the multiple scale modeling method. A substantial section is taken up with introducing the bridging scale method, which is backed up with a chapter on numerical examples using this technique. Analysis of materials applications and bio-inspired applications, using and testing the multiple scale modeling method, concludes the text.
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.
