Original Abstract

Constitutive models of aortic wall are important for its biomechanical analyses. Although structure based constitutive models are considered preferable, the lack of histological data on tissue structure is limiting and sometimes they are fitted to mechanical tests only [3]. This study compares the capability of different structure-based constitutive models to fit the mechanical tests with and without histological data. For this purpose, the most common models of arterial wall tissues were used, both postulating two fibre families, with (GOH [1]) and without (HGO [2]) dispersion of their directions. The differences between the investigated constitutive models are illustrated using finite element simulations
