Material models of healthy, intermediate and aged aortic wall for simulation of traumatic rupture of aorta.

The article presents a study that examined the use of aortic wall constitutive models for simulation of traumatic rupture of aorta. It cites that two isotropic material laws were used, namely the strain energy density function (SEDF) law for healthy and intermediate aortic tissues and a basic elastic law for aged aortic tissue. It indicates that the intermediate and aged thresholds should be more effective for bidirectional load of the aortic tissue.
