Practical multiscaling Practical Multiscaling covers fundamental modelling techniques aimed at bridging diverse temporal and spatial scales ranging from the atomic level to a full scale product level. It focuses on practical multiscale methods that account for fine scale (material) details but do not require their precise resolution. The text material evolved from over 20 years of teaching experience at Rensselaer and Columbia University as well as from practical experience gained in the application of multiscale software. This book comprehensively covers theory and implementation providing a detailed exposition of the state of the art multiscale theories and their insertion into conventional (single scale) finite element code architecture. The robustness and design aspects of multiscale methods are also emphasised which is accomplished via four building blocks: upscaling of information systematic reduction of information characterization of information utilizing experimental data and material optimization. To ensure the reader gains hands on experience a companion website hosting a lite version of the multiscale design software (MDS Lite) is available. Key features: Combines fundamental theory and practical methods of multiscale modelling Covers the state of the art multiscale theories and examines their practical usability in design; covers applications of multiscale methods; accompanied by a continuously updated website hosting the multiscale design software; illustrated with colour images. Practical Multiscaling is an ideal textbook for graduate students studying multiscale science and engineering. It is also a must have reference for government laboratories researchers and practitioners in civil aerospace pharmaceutical electronics and automotive industries and commercial software vendors
