Full Description
This book covers all aspects of materials with negative Poisson's ratio - auxetic materials - and includes some aspects of materials with negative thermal expansivity (NTE), negative refractive index (NRI) and negative stiffness (NS). It will describe the state of the art in i) modelling of the fundamental mechanisms driving auxetic and other related anomalous behaviours, ii) the range of physical properties found in these materials and the techniques used to measure them, iii) the current and possible future applications for these materials and how these applications exploit their anomalous properties, iv) processing methods for the manufacture of such materials.Featuring an author team headed by the pioneers of the field, and aimed at graduate engineers, materials scientists, chemists and physicists, the book will be of interest to those in academic or industrial research.
