Journal ArticleDOI
Biomechanical behavior of the arterial wall and its numerical characterization
TL;DR: By using the new material model the study shows a significant improvement in approaching the experimental stress-strain data within the entire pressure domain and for various levels of prestretch encompassing physiological pressures and the individual in vivo axial prestretches.
Journal ArticleDOI
Analysis of the passive mechanical properties of rat carotid arteries
TL;DR: There is a characteristic deformation pattern common to all vessels investigated which is highly correlated with the conditions of loading that occur in vivo, and under average physiological deformation of the vessel, the longitudinal force is nearly independent of internal pressure.
Journal ArticleDOI
Large strain analysis of soft biological membranes: Formulation and finite element analysis
TL;DR: In this article, a general formulation of thin incompressible membranes and the behavior of soft biotissues using the finite element method is presented, in particular the underlying hyperelastic model is chosen to examine the highly non-linear constitutive relation of blood vessels.
Journal ArticleDOI
Isotropy and anisotropy of the arterial wall.
TL;DR: The passive biomechanical response of intact cylindrical rat carotid arteries is studied in vitro and compared with the mechanical response of rubber tubes, showing that while rubber response can be adequately represented as linearly elastic and isotropic, the overall response of vascular tissue is highly non-linear and anisotropic.
Journal ArticleDOI
A new axisymmetrical membrane element for anisotropic, finite strain analysis of arteries
TL;DR: In this article, a constitutive modeling and numerical analysis of vascular segments covering finite strains is presented, with special attention paid to a two term potential that constitutes an essential foundation for accurate simulation within the entire strain domain.
