Electro-mechanical wrinkling of soft dielectric films bonded to hyperelastic substrates
Bin Wu, Linghao Kong, Weiqiu Chen +2
Active control of wrinkling in soft film-substrate composites using electric fields is a critical challenge in tunable material systems. Here, we investigate the electro-mechanical…
Programmable wrinkling for functionally-graded auxetic circular membranes
Sairam Pamulaparthi Venkata, Valentina Balbi, Michel Destradea +2
Materials with negative Poisson's ratio, also known as auxetic materials, display exotic properties such as expansion in all directions under uni-axial tension. For their unique pr…
Canceling the elastic Poynting effect with geometry
M. Destrade, Y. Du, J. Blackwell +2
The Poynting effect is a paragon of nonlinear soft matter mechanics. It is the tendency (found in all incompressible, isotropic, hyperelastic solids) exhibited by a soft block to e…
Non-invasive measurement of local stress inside soft materials with programmed shear waves
Zhaoyi Zhang, Guo-Yang Li, Yuxuan Jiang +4
Mechanical stresses in soft materials across different length scales play a fundamental role in understanding the function of biological systems and in the use of artificial materi…
Elastic wave propagation in magneto-active fibre composites
Harold Berjamin, Stephan Rudykh
Fibre-reinforced elastomers are lightweight and strong materials that can sustain large deformations. When filled with magnetic particles, their effective mechanical response can b…
Modelling the non-linear viscoelastic behaviour of brain tissue in torsion
G. Small, F. Ballatore, C. Giverso +1
Brain tissue accommodates non-linear deformations and exhibits time-dependent mechanical behaviour. The latter is one of the most pronounced features of brain tissue, manifesting i…
Modelling brain tissue elasticity with the Ogden model and an alternative family of constitutive models
Afshin Anssari-Benam, Michel Destrade, Giuseppe Saccomandi
The Ogden model is often considered as a standard model in the literature for application to the deformation of brain tissue. Here we show that, in some of those applications, the…
Local and Global Dynamics of a Functionally Graded Dielectric Elastomer Plate
Amin Alibakhshi, Sasan Rahmanian, Michel Destrade +1
We investigate the nonlinear vibrations of a functionally graded dielectric elastomer plate subjected to electromechanical loads. We focus on local and global dynamics in the syste…
Voltage-controlled non-axisymmetric vibrations of soft electro-active tubes with strain-stiffening effect
F. Zhu, B. Wu, M. Destrade +3
Material properties of soft electro-active (SEA) structures are significantly sensitive to external electro-mechanical biasing fields (such as pre-stretch and electric stimuli), wh…
Designing necks and wrinkles in inflated auxetic membranes
Sairam Pamulaparthi Venkata, Valentina Balbi, Michel Destrade +1
This article presents the potentiality of inflatable, functionally-graded auxetic membranes to produce wrinkles and necks. We obtain elastic instabilities at desired locations in a…
The generalised Mooney space for modelling the response of rubber-like materials
Afshin Anssari-Benam, Andrea Bucchi, Michel Destrade +1
Soft materials such as rubbers, silicones, gels and biological tissues have a nonlinear response to large deformations, a phenomenon which in principle can be captured by hyperelas…
Universality of the angled shear wave identity in soft viscous solids
Harold Berjamin, Artur L. Gower
Mechanical stress within biological tissue can indicate an anomaly, or can be vital of its function, such as stresses in arteries. Measuring these stresses in tissue is challenging…
Computation of viscoelastic shear shock waves using finite volume schemes with artificial compressibility
Harold Berjamin
The formation of shear shock waves in the brain has been proposed as one of the plausible explanations for deep intracranial injuries. In fact, such singular solutions emerge natur…
Singular travelling waves in soft viscoelastic solids of rate type
Harold Berjamin, Michel Destrade, Giuseppe Saccomandi
We consider shear wave propagation in soft viscoelastic solids of rate type. Based on objective stress rates, the constitutive model accounts for finite strain, incompressibility,…

Harold Berjamin, Michel Destrade
We present and review several models of fractional viscous stresses from the literature, which generalise classical viscosity theories to fractional orders by replacing total strai…

Experiments have shown that shear waves induced in brain tissue can develop into shock waves, thus providing a possible explanation of deep traumatic brain injuries. Here, we study…

The effective dynamic properties of specific periodic structures involving rubber-like materials can be adjusted by pre-strain, thus facilitating the design of custom acoustic filt…
Effect of different geometrically nonlinear strain measures on the static nonlinear response of isotropic and composite shells with constant curvature
A. Pagani, R. Azzara, B. Wu +1
The structural analysis of ultra-lightweight flexible shells and membranes may require the adoption of complex nonlinear strain-displacement relations. These may be approximated an…
