EndoCOM : Conception d un banc in vitro de simulation des anévrismes de l aorte abdominale
(2009)
(FR) Le traitement des anévrismes de l'aorte abdominale par voie endovasculaire est aujourd'hui prédominant à plus de 65 % mais comporte encore des risques. Le suivi postopératoire devient alors crucial. Le projet de ...
Inhomogeneous shear of orthotropic incompressible non-linearly elastic solids: Singular solutions and biomechanical interpretation
(Elsevier, 2009)
We present a detailed study of rectilinear shear deformation in the framework of orthotropic nonlinear elasticity, under Dirichlet and mixed-boundary conditions. We take a slab made of a soft matrix, reinforced with two ...
Bending instabilities of soft biological tissues
(Elsevier, 2009-12-15)
Rubber components and soft biological tissues are often subjected to large bending deformations while 'in service'. The circumferential line elements on the inner face of a bent block can contract up to a certain critical ...
Differences in tension and compression in the nonlinearly elastic bending of beams
(Texas Digital Library, 2009-02)
The classical flexure problem of non-linear incompressible elasticity is revisited for elastic materials whose mechanical response is different in tension and compression - the so-called bimodular materials. The flexure ...
Bimodular rubber buckles early in bending
(Elsevier, 2009-12-03)
A block of rubber eventually buckles under severe flexure, and several axial wrinkles appear on the inner curved face of the bent block. Experimental measurements reveal that the buckling occurs earlier - at lower compressive ...
Small amplitude waves and stability for a pre-stressed viscoelastic solid
(Springer, 2009)
We study the propagation of small amplitude waves superimposed on a large static deformation in a nonlinear viscoelastic material of differential type. We use bulk waves and surface waves to address the questions of ...
Surface waves and surface stability for pre-stretched, unconstrained, non-linearly elastic half-space
(Elsevier, 2009-06)
An unconstrained, non-linearly elastic, semi-infinite solid is maintained in a state of large static plane strain. A power¿law relation between the pre-stretches is assumed and it is shown that this assumption is well ...
Compact travelling waves in viscoelastic solids
(IOP Science, 2009-09-02)
We introduce a model for nonlinear viscoelastic solids, for which travelling shear waves with compact support are possible. Using analytical and numerical methods, we investigate the general case of this model, and an ...
On the Abaqus FEA model of finite viscoelasticity
(American Chemical Society, 2009-05)
Predictions of the QLV (Quasi-Linear Viscoelastic) constitutive law are compared with those of the ABAQUS viscoelastic model for two simple motions in order to highlight, in particular, their very different dissipation ...
