  • Catastrophic thinning of dielectric elastomers 

    Zurlo, G.; Destrade, Michel; DeTommasi, M.; Puglisi, G. (American Physical Society, 2017-02-15)
    We provide an energetic insight into the catastrophic nature of thinning instability in soft electroactive elastomers. This phenomenon is a major obstacle to the development of giant actuators, yet it is neither completely ...
  • Deficiencies in numerical models of anisotropic nonlinearly elastic materials 

    Ní Annaidh, Aisling; Destrade, Michel; Gilchrist, M.; Murphy, J.G. (Springer, 2013-08)
    Incompressible nonlinearly hyperelastic materials are rarely simulated in finite element numerical experiments as being perfectly incompressible because of the numerical difficulties associated with globally satisfying ...
  • Gent models for the inflation of spherical balloons 

    Mangan, Robert; Destrade, Michel (Elsevier, 2015)
    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 to explain the stretch-strain curve of a ...
  • Methodical fitting for mathematical models of rubber-like materials 

    Destrade, Michel; Saccomandi, Giuseppe; Sgura, Ivonne (The Royal Society Publishing, 2017-02-08)
    A great variety of models can describe the nonlinear response of rubber to uniaxial tension. Yet an in-depth understanding of the successive stages of large extension is still lacking. We show that the response can be ...
  • Slight compressibility and sensitivity to changes in Poisson's ratio 

    Destrade, Michel (2012)
    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 deformations, the corresponding normal stress ...
