Theoretical Study of Dynamic Viscoelastic Behaviour of Aorta under Impulsive Internal Pressure
Sudden increase in intraluminal pressure is one of the contributing factor in traumatic aortic rupture (TAR) in car crashes. At higher loading rates the response of the vessel may alter significantly due to viscoelasticity and inertia of the tissue. The goal of this study was to theoretically evaluate the significance of these factors in determining the state of stress and strain in aortic wall under high rate pressurization.
