    • Extreme softness of brain matter in simple shear 

      Destrade, Michel; Murphy, J.G.; Gilchrist, M.; Rashid, J.G.; Saccomandi, Giuseppe (Elsevier, 2015-03-13)
      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 result followed from simple shear experiments ...

    • The Poynting effect 

      Zurlo, Giuseppe; Blackwell, James; Colgan, Niall; Destrade, Michel (American Association of Physics Teachers, 2020-11-19)
      Intuition suggests that twisting a cylinder will shorten it, but here it is shown that for a cylinder of an incompressible material, like rubber, twisting will always produce elongation.
