Journal ArticleDOI
Fifty Shades of Brain: A Review on the Mechanical Testing and Modeling of Brain Tissue
TL;DR: This comprehensive review will stimulate the design of new experiments and guide the selection of appropriate constitutive models for specific applications, and propose appropriate mechanical modeling approaches that are as complex as necessary but as simple as possible.
Journal ArticleDOI
Modelling non-symmetric collagen fibre dispersion in arterial walls.
Gerhard Holzapfel,Justyna A. Niestrawska,Ray W. Ogden,Andreas J. Reinisch,Andreas Jörg Schriefl +4 more
TL;DR: A new non-symmetric dispersion model is introduced, based on the bivariate von Mises distribution, which is used to construct a new structure tensor and provides specific ranges for the dispersion parameters and shows how previous models can be deduced as special cases.
BookDOI
Biomechanics of Soft Tissue in Cardiovascular Systems
Gerhard Holzapfel,Ray W. Ogden +1 more
TL;DR: Preface.- The Cardiovascular System - Anatomy, Physiology and Cell Biology (Jay D. Humphrey, Andrew D. McCulloch).
Journal ArticleDOI
Layer-specific damage experiments and modeling of human thoracic and abdominal aortas with non-atherosclerotic intimal thickening.
TL;DR: A novel pseudo-elastic damage model, proposed to describe discontinuous softening in aortic arterial tissues, is proposed and fitting of the model with and without consideration of damage accumulation in the non-collagenous matrix material reveals that tissue damage is primarily related to the collagen fiber fabric.
Journal ArticleDOI
Modelling the layer-specific three-dimensional residual stresses in arteries, with an application to the human aorta
Gerhard Holzapfel,Ray W. Ogden +1 more
TL;DR: The theoretical framework developed herein enables the state of residual Stress to be calculated directly, serves to improve insight into the mechanical response of an unloaded artery wall and can be extended to accommodate more general geometries, kinematics and states of residual stress as well as more general constitutive models.
