Produktbeschreibung

MULTISCALE BIOMECHANICS Model biomechanical problems at multiple scales with this cutting-edge technology Multiscale modelling is the set of techniques used to solve physical problems which exist at multiple scales either in space or time. It has been shown to have significant applications in biomechanics, the study of biological systems and their structures, which exist at scales from the macroscopic to the microscopic and beyond, and which produce a myriad of overlapping problems. The next generation of biomechanical researchers therefore has need of the latest multiscale modelling techniques. Multiscale Biomechanics offers a comprehensive introduction to these techniques and their biomechanical applications. It includes both the theory of multiscale biomechanical modelling and its practice, incorporating some of the latest research and surveying a wide range of multiscale methods. The result is a thorough yet accessible resource for researchers looking to gain an edge in their biomechanical modelling. Multiscale Biomechanics readers will find: * Practical biomechanical applications for a variety of multiscale methods * Detailed discussion of soft and hard tissues, and more * An introduction to analysis of advanced topics ranging from stenting, drug delivery systems, and artificial intelligence in biomechanics Multiscale Biomechanics is a useful reference for researchers and scientists in any of the life sciences with an interest in biomechanics, as well as for graduate students in mechanical, biomechanical, biomedical, civil, material, and aerospace engineering.
