Journal ArticleDOI
Comparison of a multi-layer structural model for arterial walls with a fung-type model, and issues of material stability.
TL;DR: The constitutive law is examined for the description of the (passive) highly nonlinear and anisotropic response of healthy elastic arteries introduced recently by the authors to provide a new set of material parameters that can be used in a finite element program.
Journal ArticleDOI
Mechanics of the brain: perspectives, challenges, and opportunities
Alain Goriely,Mgd Marc Geers,Gerhard Holzapfel,Jayaratnam Jayamohan,Antoine Jérusalem,Sivabal Sivaloganathan,W Waney Squier,Jaw Hans van Dommelen,Sarah L. Waters,Ellen Kuhl +9 more
TL;DR: It is shown that classical mechanical concepts including deformations, stretch, strain, strain rate, pressure, and stress play a crucial role in modulating both brain form and brain function.
Journal ArticleDOI
Determination of the layer-specific distributed collagen fibre orientations in human thoracic and abdominal aortas and common iliac arteries
Andreas Jörg Schriefl,Georg Zeindlinger,David M. Pierce,Peter Regitnig,Gerhard Holzapfel,Gerhard Holzapfel +5 more
TL;DR: All data, except for the media of the common iliac arteries, showed two prominent collagen fibre families for all layers so that two-fibre family models seem most appropriate.
Journal ArticleDOI
A layer-specific three-dimensional model for the simulation of balloon angioplasty using magnetic resonance imaging and mechanical testing.
TL;DR: The proposed approach provides a tool that has the potential to improve procedural protocols and the design of interventional instruments on a lesion-specific basis, and to determine postangioplasty mechanical environments, which may be correlated with restenosis responses.
Journal ArticleDOI
Mechanics, mechanobiology, and modeling of human abdominal aorta and aneurysms.
TL;DR: Data on the structure and function of the human abdominal aorta and aneurysmal wall is reviewed, past models of the mechanics, and recent growth and remodeling models are reviewed, and open problems are identified that will motivate studies to improve computational modeling and thus general understanding of AAAs.
