Journal ArticleDOI
A new constitutive framework for arterial wall mechanics and a comparative study of material models
TL;DR: In this paper, the authors developed a constitutive law for the description of the (passive) mechanical response of arterial tissue, where the artery is modeled as a thick-walled nonlinearly elastic circular cylindrical tube consisting of two layers corresponding to the media and adventitia.
Book
Nonlinear Solid Mechanics: A Continuum Approach for Engineering
TL;DR: In this paper, the authors introduce the concept of stress and balance principles for tensors and invariance of tensors in the context of Vectors and Tensors, and present a survey of the main aspects of objectivity.
Journal ArticleDOI
Hyperelastic modelling of arterial layers with distributed collagen fibre orientations
TL;DR: A structural continuum framework that is able to represent the dispersion of the collagen fibre orientation is developed and allows the development of a new hyperelastic free-energy function that is particularly suited for representing the anisotropic elastic properties of adventitial and intimal layers of arterial walls.
Journal ArticleDOI
Determination of layer-specific mechanical properties of human coronary arteries with nonatherosclerotic intimal thickening and related constitutive modeling
TL;DR: The study showed the need to model nonstenotic human coronary arteries with nonatherosclerotic intimal thickening as a composite structure composed of three solid mechanically relevant layers with different mechanical properties.
Journal ArticleDOI
Constitutive modelling of passive myocardium: A structurally-based framework for material characterization
Gerhard Holzapfel,Ray W. Ogden +1 more
TL;DR: In this article, a structural model for the left ventricular myocardium is proposed, based on the invariants associated with the three mutually orthogonal directions of the myocardia.
