The mechanics of biological tissues is a multidisciplinary and rapidly expanding area of research. The book points to important directions combining mechanical sciences with the exciting new developments in biology. It delivers state-of-the-art articles on: Mechanics of tissues at the molecular, cellular, tissue and organ levels. Mechanobiology, with particular reference to growth, remodeling, repair and aging. Experimental, microstructural and continuum mechanical perspectives with an emphasis on modelling, and simulating therapeutic and diagnostic procedures. Implementation of mechanical models in numerical codes to provide a tool for the design and development of prostheses. Numerical models have the potential to greatly improve diagnostics and therapeutical procedures that involve tissue mechanics.
