    • 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 ...

    • A high rate tension device for characterizing brain tissue 

      Destrade, Michel (SAGE Journals, 2012-03-08)
      The mechanical characterization of brain tissue at high loading velocities is vital for understanding and modeling traumatic brain injury. The most severe form of traumatic brain injury is diffuse axonal injury, which ...

    • Initial stress symmetry and its applications in elasticity 

      Gower, Artur Lewis; Destrade, Michel (The Royal Society, 2015-10-28)
      An initial stress within a solid can arise to support external loads or from processes such as thermal expansion in inert matter or growth and remodelling in living materials. For this reason, it is useful to develop a ...

    • On residual stresses and homeostasis: an elastic theory of functional adaptation in living matter 

      Ciarletta, Pasquale; Destrade, Michel; Gower, Artur L. (Nature Publishing Group, 2016-04-26)
      Living matter can functionally adapt to external physical factors by developing internal tensions, easily revealed by cutting experiments. Nonetheless, residual stresses intrinsically have a complex spatial distribution, ...
