    • 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 ...
    • Phase behaviour of self-assembled monolayers controlled by tuning physisorbed and chemisorbed states: A lattice-model view 

      Cheung, David L. (American Institute of Physics, 2016-04-07)
      The self-assembly of molecules on surfaces into 2D structures is important for the bottom-up fabrication of functional nanomaterials, and the self-assembledstructure depends on the interplay between molecule-molecule ...
    • Piezoacoustic wave spectra using improved surface impedance matrix: Application to high impedance-contrast layered plates 

      Destrade, Michel (2008)
      Starting from the general modal solutions for a homogeneous layer of arbitrary material and crystalline symmetry, a matrix formalism is developed to establish the semianalytical expressions of the surface impedance matrices ...
    • Piezoelectric Love waves on rotated Y-cut mm2 substrates 

      Destrade, Michel (IEEE, 2006-11)
      Consider a layer consisting of a m3m dielectric crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For an X- or Y-cut of the substrate, a Love wave can ...
    • Poynting effect of brain matter in torsion 

      Balbi, Valentina; Trotta, Antonia; Destrade, Michel; Annaidh, Aisling Ni (Royal Society of Chemistry, 2019-06-13)
      We investigate experimentally and model theoretically the mechanical behaviour of brain matter in torsion. Using a strain-controlled rheometer, we perform torsion tests on fresh porcine brain samples. We quantify the torque ...
    • Proper formulation of viscous dissipation for nonlinear waves in solids 

      Destrade, Michel (Acoustical Society of America, 2013-03)
      To model nonlinear viscous dissipative motions in solids, acoustical physicists usually add terms the material time derivative of the Lagrangian strain tensor E, to the elastic stress tensor; derived from the expansion to ...
    • A quiver presentation for Solomon's descent algebra 

      Pfeiffer, Götz (Elsvier, 2009)
      The descent algebra S(W) is a subalgebra of the group algebra of a finite Coxeter group W, which supports a homomorphism with nilpotent kernel and commutative image in the character ring of W. Thus S(W) is a basic algebra, ...
    • Rational Generalised Moonshine from Abelian Orbifoldings of the Moonshine Module 

      Ivanov, Rossen I.; Tuite, Michael P. (2001)
      We consider orbifoldings of the Moonshine Module with respect to the abelian group generated by a pair of commuting Monster group elements with one of prime order $p=2,3,5,7$ and the other of order $pk$ for $k=1$ or $k$ ...
    • Ray W Ogden: An Appreciation 

      Destrade, Michel; Dorfmann, Luis (SAGE Publications, 2015-07)
      This special issue of Mathematics and Mechanics of Solids is dedicated to Professor Ray Ogden FRS on the occasion of his 70th birthday. It is a companion volume to another special issue edited by our colleagues ...
    • Rayleigh waves and surface stability for Bell materials in compression; comparison with rubber 

      Destrade, Michel (Oxford University Press, 2003)
      The stability of a Bell-constrained half-space in compression is studied. To this end, the propagation of Rayleigh waves on the surface of the material when it is maintained in a static state of triaxial prestrain is ...
    • Rayleigh waves in symmetry planes of crystals : explicit secular equations and some explicit wave speeds 

      Destrade, Michel (Elsevier, 2003)
      Rayleigh waves are considered for crystals possessing at least one plane of symmetry. The secular equation is established explicitly for surface waves propagating in any direction of the plane of symmetry, using two different ...
    • Realizing a fusion system by a single finite group 

      Park, Sejong (2010)
      We show that every saturated fusion system can be realized as a full subcategory of the fusion system of a finite group. The result suggests the definition of an 'exoticity index' and raises some other questions which we discuss.
    • A refinement of a conjecture of Quillen 

      Rahm, Alexander D. (Elsevier ScienceDirect, 2015-09)
      We present some new results on the cohomology of a large scope of SL2 groups in degrees above the virtual cohomological dimension, yielding some partial positive results for the Quillen conjecture in rank one. We combine ...
    • Rivlin's legacy in continuum mechanics and applied mathematics 

      Destrade, Michel; Murphy, Jeremiah; Saccomandi, Giuseppe (The Royal Society, 2019-03-18)
      Over a long and distinguished career, Ronald Rivlin (figure 1) published more than 200 scientific papers. He was a highly innovative scientist who made seminal contributions in all areas of continuum mechanics. He was one ...
    • Scalar evolution equations for shear waves in incompressible solids: a simple derivation of the Z, ZK, KZK and KP equations 

      Destrade, Michel (The Royal Society, 2011-07-08)
      We study the propagation of two-dimensional finite-amplitude shear waves in a nonlinear pre-strained incompressible solid, and derive several asymptotic amplitude equations in a simple, consistent and rigorous manner. The ...
    • Seismic Rayleigh waves on an exponentially graded, orthotropic half-space 

      Destrade, Michel (The Royal Society, 2007)
      Efforts at modelling the propagation of seismic waves in half-spaces with continuously varying properties have mostly been focused on shear-horizontal waves. Here, a sagittally polarized (Rayleigh type) wave travels along ...
    • Shear instability in skin tissue 

      Ciarletta, Pasquale; Destrade, Michel; Gower, Artur L. (Oxford University Press, 2013)
      We propose two toy-models to describe, predict and interpret the wrinkles appearing on the surface of skin when it is sheared. With the first model, we account for the lines of greatest tension present in human skin by ...
    • Simple shear is not so simple 

      Destrade, Michel (2012-03)
      For homogeneous, isotropic, non-linearly elastic materials, the form of the homogeneous deformation consistent with the application of a Cauchy shear stress is derived here for both compressible and incompressible materials. ...
    • 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 ...
    • Small amplitude waves and stability for a pre-stressed viscoelastic solid 

      Destrade, Michel (Springer, 2009)
      We study the propagation of small amplitude waves superimposed on a large static deformation in a nonlinear viscoelastic material of differential type. We use bulk waves and surface waves to address the questions of ...
