Passive and Active Deformation Processes of 3D Fibre-Reinforced Caricatures of Cardiovascular Tissues
Publié en 2009
In this paper, we present a mathematical model of contractile elastic solids meant to simulate various districts of the cardiovascular system, and based on the concepts of active deformation and embedded muscle fibres. Specifically, here we deal with the modeling of the gross mechanics of the Left Ventricle (LV) which is strictly related to its pump function. As is well known, the effectiveness of the pumping action is well represented by the Pressure-Volume (PV) diagrams that relate the blood pressure to the volume of the LV during the cardiac cycle. Here, we aim at reproducing realistic PV by specifying appropriate sequence of muscle contraction.
