  • 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 ...
  • On the third- and fourth-order constants of incompressible isotropic elasticity. 

    Destrade, Michel (Acoustical Society of America, 2010-04-25)
    Consider the constitutive law for an isotropic elastic solid with the strain-energy function expanded up to the fourth order in the strain and the stress up to the third order in the strain. The stress-strain relation can ...
  • 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 ...
  • Third and fourth-order elasticity of biological soft tissues 

    Destrade, Michel; Gilchrist, Michael D. (Acoustical Society of America, 2010-01-24)
    In the theory of weakly nonlinear elasticity, Hamilton et al. [J. Acoust. Soc. Am. 116, 41-44 (2004)] identified W = -I2+(A/3)I3+DI22 as the fourth-order expansion of the strain-energy density for incompressible isotropic ...
  • Third- and fourth-order constants of incompressible soft solids and the acousto-elastic effect. 

    Destrade, Michel; Gilchrist, Michael D. (Acoustical Society of America, 2010-02)
    Acousto-elasticity is concerned with the propagation of small-amplitude waves in deformed solids. Results previously established for the incremental elastodynamics of exact non-linear elasticity are useful for the determination ...
