Multiscale Plasticity

Multiscale Plasticity Nasr M Ghoniem and Giacomo Po, UCLA, USA A comprehensive treatment of plastic deformation at multiple length scales Plastic deformation is an important subject as a result of the wide use of metals in many technological applications, the fact that it is associated with failure mechanisms, and because of the emergence of strain engineering in the microelectronics industry. Plasticity is also becoming a significant factor in the design of nano and micro systems. Multiscale Plasticity addresses the subject of plasticity in a comprehensive manner, utilizing the multiscale modelling of materials (MMM) approach to systematically reduce the degrees of freedom at natural length scales. At the atomic scale, computer simulation methods, such as Molecular Dynamics (MD) and the Kinetic Monte Carlo (KMC) are presented. The book then discusses the role played by Dislocation Dynamics (DD) and Statistical Mechanics (SM) methods in understanding microstructure self-organization, heterogeneous plastic deformation, material instabilities and failure phenomena. At the macro-scale, emphasis is placed on recent progress made in crystal plasticity, strain gradient elasticity, strain gradient plasticity, and homogenization techniques. Key Features: Presents a physically based approach to the description of plasticity. Modern computational methods are introduced to the reader at multiple length scales, from the atoms all the way up to the continuum level. Direct comparisons between experiment and multiscale modelling. Applications are given in nano and micro-technologies, as well as examples of materials-by-design. Pedagogical in nature, Multiscale Plasticity leads the reader to a more in-depth understanding of plasticity at all length scales for a wide range of applications.
