Modeling sarcopenia: a geriatric disease of skeletal muscle tissue

Risultato della ricerca: Contributo in libroContributo a convegno

Abstract

We propose a continuum model of skeletal muscle tissue with a reduced performance due to ageing. The passive behavior of the material is described by a hyperelastic, polyconvex, transversely isotropic strain energy function, and the activation of the muscle is modeled by the so called active strain approach. The loss of ability of activating of an elder muscle is then obtained by lowering of some percentage the active part of the stress, while the loss of mass is modeled through a multiplicative decomposition of the deformation gradient.
