Despite their many common features (mechanical behavior, multi-scale structure, evolutionary and living characteristics, etc.), the tissues that make up the human body each have specific characteristics linked to their function, which require the development of dedicated experimental, theoretical and numerical methods. Mechanics of Living Tissues brings together the work of a number of experts to provide an overview of the most recent approaches developed to study the biomechanical behavior of these soft tissues, in order to understand their structure and apparent behavior. Specific tissues are analyzed across the chapters with the aim of developing solutions that address the clinical problems encountered. Conclusions are then drawn regarding future methods that will improve the current state of knowledge of the behavior of these living tissues, in particular with a view to predicting the effect of a pathology or medical procedure on their apparent properties.
