  • NHDC and PHDC: Non-propagating and propagating heat diffusion classifiers 

    Yang, Haixuan (12th International Conference on Neural Information Processing, 2005)
    Abstract - By imitating the way that heat flows in a medium with a geometric structure, we propose two novel classification algorithms, Non-propagating Heat Diffusion Classifier (NHDC) and Propagating Heat Diffusion ...
  • Non-principal surface waves in deformed incompressible materials 

    Destrade, Michel (Elsevier, 2005)
    The Stroh formalism is applied to the analysis of infinitesimal surface wave propagation in a statically, finitely and homogeneously deformed isotropic half-space. The free surface is assumed to coincide with one of the ...
  • Nonlinear correction to the Euler buckling formula for compressed cylinders with guided-guided end conditions 

    Destrade, Michel (Springer, 2011-02)
    Euler's celebrated buckling formula gives the critical load N for the buckling of a slender cylindrical column with radius B and length L as N/([pi]^3 B^2 )=(E/4)(B/L)^2, where E is Young's modulus. Its derivation relies ...
  • Nonlinear Euler buckling 

    Goriely, Alain; Vandiver, Rebecca; Destrade, Michel (Royal Society Publishing, 2008-11)
    The buckling of hyperelastic incompressible cylindrical tubes of arbitrary length and thickness under compressive axial load is considered within the framework of nonlinear elasticity. Analytical and numerical methods for ...
  • Nonlinear transverse waves in deformed dispersive solids 

    Destrade, Michel (Elsevier, 2008)
    We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) properties of a hyperelastic dispersive ...
  • A note about waves in dissipative and dispersive solids 

    Destrade, Michel; Saccomandi, Giuseppe (World Scientific, 2008)
    We study shear waves propagating in a special viscoelastic model proposed first by Fosdick and Yu in 1996. We deduce an asymptotic approximation which reduces the full balance equations to a system of evolution equations ...
  • On a question of Serre 

    Rahm, Alexander D. (2012)
    Consider an imaginary quadratic number field Q(root -m), with m a square-free positive integer, and its ring of integers {O} . The Bianchi groups are the groups SL2{O}. Further consider the Borel-Serre compactification [7] ...
  • On anisotropic elasticity and questions concerning its Finite Element implementation 

    Vergori, Luigi; Destrade, Michel; McGarry, Patrick; Ogden, Ray W. (Springer, 2013-05-21)
    We give conditions on the strain-energy function of nonlinear anisotropic hyperelastic materials that ensure compatibility with the classical linear theories of anisotropic elasticity. We uncover the limitations associated ...
  • On deforming a sector of a circular cylindrical tube into an intact tube: Existence, uniqueness, and stability 

    Destrade, Michel (Elsevier, 2010-11)
    Within the context of finite deformation elasticity theory the problem of deforming an open sector of a thick-walled circular cylindrical tube into a complete circular cylindrical tube is analyzed. The analysis provides a ...
  • On Genus Two Riemann Surfaces Formed from Sewn Tori 

    Mason, Geoffrey; Tuite, Michael P. (2006)
    We describe the period matrix and other data on a higher genus Riemann surface in terms of data coming from lower genus surfaces via an explicit sewing procedure. We consider in detail the construction of a genus two Riemann ...
  • On Level One Cuspidal Bianchi Modular Forms 

    Rahm, Alexander D. (2013)
    In this paper, we present the outcome of vast computer calculations, locating several of the very rare instances of level one cuspidal Bianchi modular forms that are not lifts of elliptic modular forms.
  • On magneto-acoustic waves in finitely deformed elastic solids 

    Destrade, Michel (SAGE Journals, 2011)
    In this paper, in the context of the quasi-magnetostatic approximation, we examine incremental motions superimposed on a static finite deformation of a magneto-elastic material in the presence of an applied magnetic field. ...
  • 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, ...
  • On stress-dependent elastic moduli and wave speeds 

    Destrade, Michel (Oxford Journals, 2012-03-30)
    On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
  • On stress-dependent elastic moduli and wave speeds 

    Destrade, Michel; Ogden, R.W. (Oxford University Press, 2013)
    On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
  • On the Abaqus FEA model of finite viscoelasticity 

    Destrade, Michel (American Chemical Society, 2009-05)
    Predictions of the QLV (Quasi-Linear Viscoelastic) constitutive law are compared with those of the ABAQUS viscoelastic model for two simple motions in order to highlight, in particular, their very different dissipation ...
  • On the application of robust numerical methods to a complete flow wave-current model. Boundary and Interior Layers ONERA 

    Madden, Niall (2004)
    We aim to show how parameter-robust numerical method may be employed to solve equations arising in the modelling of wave-current interactions.We present two such models: a complete flow model for wave-current interaction ...
  • On the composition product of saturated fusion systems 

    Park, Sejong (Elsevier, 2011-11)
    We say that a fusion system is the composition product of two subsystems if every morphism can be factored as a morphism in one fusion system followed by a morphism in the other. We establish a relationship between the ...
  • On the equivariant K-homology of PSL_2 of the imaginary quadratic integers 

    Rahm, Alexander D. (Association des Annales de l'Institut Fourier, 2016-09)
    We establish formulae for the part due to torsion of the equivariant $K$-homology of all the Bianchi groups (PSL$_2$ of the imaginary quadratic integers), in terms of elementary number-theoretic quantities. To achieve this, ...
  • On the rectilinear shear of compressible and incompressible elastic slabs 

    Destrade, Michel (2010)
    We review some pseudo-planar deformations for the equations of incompressible isotropic nonlinear elasticity first introduced in 1985 by Rajagopal and Wineman. We extend this class of deformations to compressible isotropic ...
