Comparison of a multi-layer structural model for arterial walls with a fung-type model, and issues of material stability
2004 (English)In: Journal of Biomechanical Engineering, ISSN 0148-0731, Vol. 126, no 2, 264-275 p.Article in journal (Refereed) Published
Abstract [en]

The goals of this paper are (i) to re-examine the constitutive law for the description of the (passive) highly nonlinear and anisotropic response of healthy elastic arteries introduced recently by the authors, (ii) to show how the mechanical response of a carotid artery under inflation and extension predicted by the structural model compares with that for a three-dimensional form of Fung-type strain-energy function, (iii) to provide a new set of material parameters that can be used in a finite element program, and (iv) to show that the model has certain mathematical features that are important from the point of view of material and numerical stability.
