Conduit arteries become stiffer with age due to alterations in their morphology and the
composition of the their major structural proteins, elastin and collagen. The elastic lamellae …

A stress-driven model for the relation between the collagen morphology and the loading
conditions in arterial walls is proposed. We assume that the two families of collagen fibers in …

Arteries display a nonlinear anisotropic behavior dictated by the elastic properties and
structural arrangement of its main constituents, elastin, collagen, and vascular smooth …

The present study addresses constitutive modelling and implementation of transversely
isotropic hyper‐elastic material models for the analysis of the mitral valve. This valve …

In this paper a generalized anisotropic hyperelastic constitutive model for fiber-reinforced
materials is proposed. Collagen fiber alignment in biological tissues is taken into account by …

Passive elastic behavior of arterial wall remains difficult to model. Although
phenomenological and structural models exist, the question of how the three-dimensional …

BACKGROUND: Changes in the mechanical behavior of arteries after balloon angioplasty
cause cell reactions that may be responsible for restenosis. Hence, the study of the stress …

A new remodeling theory accounting for mechanically driven collagen fiber reorientation in
cardiovascular tissues is proposed. The constitutive equations for the living tissues are …

A micromechanically based constitutive model for fibrous tissues is presented. The model
considers the randomly crimped morphology of individual collagen fibers, a morphology …

Balloon angioplasty intervention is traumatic to arterial tissue. Fracture mechanisms such as
plaque fissuring and/or dissection occur and constitute major contributions to the lumen …
