Blood Vessel

This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal surfaces producing deformation of the vessel walls.

The complete analysis consists of two distinct but coupled procedures: a fluid-dynamics analysis with the calculation of the velocity field and pressure distribution in the blood (variable in time and in space) and the mechanical analysis with the deformation of the tissue and artery. The material is assumed to be nonlinear and a hyperelastic model is used.

A blood vessel, embedded in a biological tissue, is deformed during the flow of blood through pressure applied to the internal surfaces. The model consists of a fluid-dynamics analysis with the calculation of the velocity field and pressure distribution in the blood along with a mechanical analysis of the tissue and artery.
