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,…
Extreme softness of brain matter in simple shear
Michel Destrade, Michael D. Gilchrist, Jerry G. Murphy +2
We show that porcine brain matter can be modelled accurately as a very soft rubber-like material using the Mooney-Rivlin strain energy function, up to strains as high as 60\%. This…
Deficiencies in numerical models of anisotropic nonlinearly elastic materials
Aisling Ni Annaidh, Michel Destrade, Michael D. Gilchrist +1
Incompressible nonlinearly hyperelastic materials are rarely simulated in Finite Element numerical experiments as being perfectly incompressible because of the numerical difficulti…
At least three invariants are necessary to model the mechanical response of incompressible, transversely isotropic materials
Michel Destrade, Brian Mac Donald, Jerry Murphy +1
The modelling of off-axis simple tension experiments on transversely isotropic nonlinearly elastic materials is considered. A testing protocol is proposed where normal force is app…
Slight compressibility and sensitivity to changes in Poisson's ratio
Michel Destrade, Michael D. Gilchrist, Julie Motherway +1
Finite Element simulations of rubbers and biological soft tissue usually assume that the material being deformed is slightly compressible. It is shown here that in shearing deforma…
On deforming a sector of a circular cylindrical tube into an intact tube: existence, uniqueness, and stability
Micehl Destrade, Jerry G. Murphy, Ray W. Ogden
Within the context of finite deformation elasticity theory the problem of deforming an open sector of a thick-walled circular cylindrical tube into a complete circular cylindrical…
