Bending control and instability of functionally graded dielectric elastomers
Yipin Su, Ray W. Ogden, Michel Destrade
A rectangular plate of dielectric elastomer exhibiting gradients of material properties through its thickness will deform inhomogeneously when a potential difference is applied to…
On the thermodynamic consistency of Quasi-Linear Viscoelastic models for soft solids
Harold Berjamin, Michel Destrade, William J. Parnell
Originating in the field of biomechanics, Fung's model of quasi-linear viscoelasticity (QLV) is one of the most popular constitutive theories employed to compute the time-dependent…
Torsion instability of soft solid cylinders
Pasquale Ciarletta, Michel Destrade
The application of pure torsion to a long and thin cylindrical rod is known to provoke a twisting instability, evolving from an initial kink to a knot. In the torsional parallel-pl…
Straightening: Existence, uniqueness and stability
Michel Destrade, Ray W. Ogden, Ivonne Sgura +1
One of the least studied universal deformations of incompressible nonlinear elasticity, namely the straightening of a sector of a circular cylinder into a rectangular block, is rev…
Gent models for the inflation of spherical balloons
Robert Mangan, Michel Destrade
We revisit an iconic deformation of non-linear elasticity: the inflation of a rubber spherical thin shell. We use the 3-parameter Mooney and Gent-Gent (GG) phenomenological models…
Dominant negative Poynting effect for soft tissues
Michel Destrade, Cornelius O. Horgan, Jerry G. Murphy
We identify three distinct shearing modes for simple shear deformations of transversely isotropic soft tissue which allow for both positive and negative Poynting effects (that is,…
