Mechanical characterization of brain tissue in simple shear at dynamic strain rates
(Elsevier, 2013-12)
During severe impact conditions, brain tissue experiences a rapid and complex deformation, which can be seen as a mixture of compression, tension and shear. Diffuse axonal injury (DAI) occurs in animals and humans when ...
On anisotropic elasticity and questions concerning its Finite Element implementation
(Springer, 2013-05-21)
We give conditions on the strain-energy function of nonlinear anisotropic hyperelastic materials that ensure compatibility with the classical linear theories of anisotropic elasticity. We uncover the limitations associated ...
Deficiencies in numerical models of anisotropic nonlinearly elastic materials
(Springer, 2013-08)
Incompressible nonlinearly hyperelastic materials are rarely simulated in finite element numerical experiments as being perfectly incompressible because of the numerical difficulties associated with globally satisfying ...
On stress-dependent elastic moduli and wave speeds
(Oxford University Press, 2013)
On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
Catastrophic thinning of dielectric elastomers
(American Physical Society, 2017-02-15)
We provide an energetic insight into the catastrophic nature of thinning instability in soft electroactive elastomers. This phenomenon is a major obstacle to the development of giant actuators, yet it is neither completely ...
Onde de Love Piézoacoustique
(2006-04-24)
Une sélection de résultats analytiques et numériques concernant la propagation d'ondes planes harmoniques guidées dans un bicouche piézoélectrique est présentée.
L'étude effectuée concerne les modes transverses horizontaux ...
Ray W Ogden: An Appreciation
(SAGE Publications, 2015-07)
This special issue of Mathematics and Mechanics of Solids is dedicated to Professor Ray Ogden FRS on the occasion
of his 70th birthday. It is a companion volume to another special issue edited by our colleagues ...
On residual stresses and homeostasis: an elastic theory of functional adaptation in living matter
(Nature Publishing Group, 2016-04-26)
Living matter can functionally adapt to external physical factors by developing internal tensions, easily revealed by cutting experiments. Nonetheless, residual stresses intrinsically have a complex spatial distribution, ...
Wireless communicative stent for follow-up of abdominal aortic aneurysm,
(IEEE, 2006)
An abdominal aortic aneurysm (AAA) is a dilatation of the aorta at the abdominal level, which rupture is a life threatening complication. Recent treatment of AAA consists in endovascular treatment with covered stent grafts. ...
Strain energy function for isotropic non-linear elastic incompressible solids with linear finite strain response in shear and torsion
(Elsevier, 2016-07-18)
We find the strain energy function for isotropic incompressible solids exhibiting a linear relationship between shear stress and amount of shear, and between torque and amount of twist, when subject to large simple shear ...
