  • Automated estimation of collagen fibre dispersion in the dermis and its contribution to the anisotropic behaviour of skin 

    Ní Annaidh, Aisling; Destrade, Michel; Gilchrist, Michael D. (Springer, 2012-08)
    Collagen fibres play an important role in the mechanical behaviour of many soft tissues. Modelling of such tissues now often incorporates a collagen fibre distribution. However, the availability of accurate structural data ...
  • Bimodular rubber buckles early in bending 

    Destrade, Michel; Gilchrist, Michael D.; Motherway, Julie A. (Elsevier, 2009-12-03)
    A block of rubber eventually buckles under severe flexure, and several axial wrinkles appear on the inner curved face of the bent block. Experimental measurements reveal that the buckling occurs earlier - at lower compressive ...
  • Characterising the anisotropic mechanical properties of excised human skin 

    Ní Annaidh, Aisling; Destrade, Michel; Gilchrist, Michael D. (2012)
    The mechanical properties of skin are important for a number of applications including surgery, dermatology, impact biomechanics and forensic science. In this study, we have investigated the influence of location and ...
  • A combined experimental and numerical study of stab-penetration forces 

    Ní Annaidh, Aisling; Cassidy, Mary; Curtis, Michael; Destrade, Michel; Gilchrist, Michael D. (Elsevier, 2013-12)
    The magnitude of force used in a stabbing incident can be difficult to quantify, although the estimate given by forensic pathologists is often seen as 'critical' evidence in medico-legal situations. The main objective of ...
  • Hyperelastic and viscoelastic properties of brain tissue in tension 

    Destrade, Michel; Gilchrist, Michael D. (ASME, 2012)
    Mechanical characterization of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ...
  • Influence of preservation temperature on the measured mechanical properties of brain tissue 

    Rashid, Badar; Destrade, Michel; Gilchrist, Michael D. (Elsevier, 2013-04-26)
    The large variability in experimentally measured mechanical properties of brain tissue is due to many factors including heterogeneity, anisotropy, age dependence and post-mortem time. Moreover, differences in test protocols ...
  • Mechanical characterization of brain tissue in compression at dynamic strain rates 

    Destrade, Michel; Gilchrist, Michael D. (Elsevier, 2012-03-02)
    Traumatic brain injury (TBI) occurs when local mechanical load exceeds certain tolerance levels for brain tissue. Extensive research has been done previously for brain matter experiencing compression at quasistatic loading; ...
  • Mechanical characterization of brain tissue in simple shear at dynamic strain rates 

    Rashid, Badar; Destrade, Michel; Gilchrist, Michael D. (Elsevier, 2013-12)
    During severe impact conditions, brain tissue experiences a rapid and complex deformation, which can be seen as a mixture of compression, tension and shear. Diffuse axonal injury (DAI) occurs in animals and humans when ...
  • Mechanical characterization of brain tissue in tension at dynamic strain rates 

    Rashid, B,Destrade, M,Gilchrist, MD; Destrade, Michel; Gilchrist, Michael D. (Elsevier, 2012-09-10)
    Mechanical characterization of brain tissue at high loading velocities is crucial for modeling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences compression, tension and shear. Limited ...
  • Mechanical properties of excised human skin 

    Ni Annaidh, Aisling; Ottenio, M.; Bruyere, K.; Destrade, Michel; Gilchrist, Michael D. (Springer Verlag, 2010)
    In this study we have investigated in influence of location, gender and orientation on the deformation characteristics of 55 samples of human excised skin. Uniaxial tensile tests were carried out at a strain rate of ...
  • Onset of non-linearity in the elastic bending of blocks 

    Destrade, Michel; Gilchrist, Michael D. (American Society of Mechanical Engineers, 2013-01-25)
    The classical flexure problem of non-linear incompressible elasticity is revisited assuming that the bending angle suffered by the block is specified instead of the usual applied moment. The general moment-bending angle ...
  • 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 ...
