Un modello matematico del tessuto muscolare

After a brief introduction of the Continuum Mechanics of Solids, some models of a muscle, which is a transversely isotropic material, are considered. A feature of this material is to produce not only a passive stress, analogous to ordinary materials, but also an active stress, needed to produce power: the main mathematical tool used to describe this phenomenon will be introduced. These kind of models could help understanding some pathologies due to ageing, like the sarcopenia, which consists in a loss of muscle mass and muscle performance.
