Journal ArticleDOI
On the tension-compression switch in soft fibrous solids
Gerhard Holzapfel,Ray W. Ogden +1 more
TL;DR: In this paper, a modified fiber distribution model is proposed for both plane strain and three-dimensional transversely isotropic fiber distributions and applied to both 3D and 4D fiber distributions.
Journal ArticleDOI
Biomechanics of aortic wall failure with a focus on dissection and aneurysm: A review.
TL;DR: It is proposed that an appropriate material failure criterion for aortic tissues should also reflect the microstructure in order to be effective and biomechanically motivated models to predict rupture risk are proposed.
Journal ArticleDOI
Modeling Plaque Fissuring and Dissection during Balloon Angioplasty Intervention
TL;DR: The predicted results indicate that plaque fissuring and dissection cause localized mechanical trauma, but prevent the main portion of the stenosis from high stress, and hence from continuous tissue damage.
Journal ArticleDOI
A three-dimensional finite element model for arterial clamping.
TL;DR: A three-dimensional finite element model is presented, which allows the study of the mechanical response of an artery-treated as a two-layer tube-during arterial clamping and has the potential to identify the most appropriate clamps for certain types of arteries and to guide optimal clamp design.
Journal ArticleDOI
The role of elastin and collagen in the softening behavior of the human thoracic aortic media
TL;DR: Testing the hypothesis that structural changes in the tissue after enzyme treatment are related only to the collagen fibers, and not to the matrix material, shows that an isotropic matrix model is sufficient to accurately reproduce the mechanical response of untreated control specimens, consistent with current practice in the literature.
