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 ...
Nonlinear transverse waves in deformed dispersive solids
(Elsevier, 2008)
We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) properties of a hyperelastic dispersive ...
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 ...
Measuring knife stab penetration into skin simulant using a novel biaxial tension device
(Elsevier, 2008)
This paper describes the development and use of a biaxial measurement device to analyse the mechanics of knife stabbings. In medicolegal situations it is typical to describe the consequences of a stabbing incident in ...
Piezoacoustic wave spectra using improved surface impedance matrix: Application to high impedance-contrast layered plates
(2008)
Starting from the general modal solutions for a homogeneous layer of arbitrary material and crystalline symmetry, a matrix formalism is developed to establish the semianalytical expressions of the surface impedance matrices ...
Incremental magnetoelastic deformations, with application to surface instability
(Springer, 2008-01)
In this paper the equations governing the deformations of infinitesimal (incremental) disturbances superimposed on finite static deformation fields involving magnetic and elastic interactions are presented. The coupling ...
