  • Oblique wrinkles 

    Carfagna, M.; Destrade, Michel; Gower, Artur L.; Grillo, A. (The Royal Society Publishing, 2017-04-03)
    We prove theoretically that when a soft solid is subjected to an extreme deformation, wrinkles can form on its surface at an angle that is oblique to a principal direction of stretch. These oblique wrinkles occur for a ...
  • Catastrophic thinning of dielectric elastomers 

    Zurlo, G.; Destrade, Michel; DeTommasi, M.; Puglisi, G. (American Physical Society, 2017-02-15)
    We provide an energetic insight into the catastrophic nature of thinning instability in soft electroactive elastomers. This phenomenon is a major obstacle to the development of giant actuators, yet it is neither completely ...
  • Elastic Cherenkov effects in transversely isotropic soft materials-I: Theoretical analysis, simulations and inverse method 

    Li, Guo-Yang; Zheng, Yang; Liu, Yanlin; Destrade, Michel; Cao, Yanping (Elsevier, 2016-06-25)
    A body force concentrated at a point and moving at a high speed can induce shear-wave Mach cones in dusty-plasma crystals or soft materials, as observed experimentally and named the elastic Cherenkov effect (ECE). The ECE ...
  • Methodical fitting for mathematical models of rubber-like materials 

    Destrade, Michel; Saccomandi, Giuseppe; Sgura, Ivonne (The Royal Society Publishing, 2017-02-08)
    A great variety of models can describe the nonlinear response of rubber to uniaxial tension. Yet an in-depth understanding of the successive stages of large extension is still lacking. We show that the response can be ...
  • Edge wrinkling in elastically supported pre-stressed incompressible isotropic plates 

    Destrade, Michel; Fu, Yibin; Nobili, Andrea (The Royal Society Publishing, 2016-09-07)
    The equations governing the appearance of flexural static perturbations at the edge of a semi-infinite thin elastic isotropic plate, subjected to a state of homogeneous bi-axial pre-stress, are derived and solved. The plate ...
  • Strain energy function for isotropic non-linear elastic incompressible solids with linear finite strain response in shear and torsion 

    Mangan, Robert; Destrade, Michel; Saccomandi, Giuseppe (Elsevier, 2016-07-18)
    We find the strain energy function for isotropic incompressible solids exhibiting a linear relationship between shear stress and amount of shear, and between torque and amount of twist, when subject to large simple shear ...
  • The annual GiG - Groups in Galway 

    Hurley, Ted (NUI Galway, 2015)
    The GiG (Groups in Galway) conference, and related activity, has been running annually since 1978 and is the longest running annual international mathematical conference on a special topic. It has its origin from the ...
  • On the Torus degeneration of the genus two partition function 

    Hurley, Donny; Tuite, Michael P. (World Scientific Publishing, 2013-07-16)
    We consider the partition function of a general vertex operator algebra V on a genus two Riemann surface formed by sewing together two tori. We consider the non-trivial degeneration limit where one torus is pinched down ...
  • 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 ...
  • 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, ...
  • 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 ...
  • The mod 2 cohomology rings of SL2 of the imaginary quadratic integers 

    Rahm, Alexander D. (Elsevier ScienceDirect, 2015-09-28)
    We establish general dimension formulae for the second page of the equivariant spectral sequence of the action of the SL2 groups over imaginary quadratic integers on their associated symmetric space. By way of doing this, ...
  • 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, ...
  • 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 ...
  • Multiples of Pfister forms 

    O'Shea, James (Elsevier, 2016-03-01)
    The isotropy of multiples of Pfister forms is studied. Some classical results are recalled and their consequences presented, with certain of these statements being previously known but hitherto unpublished. In particular, ...
  • Toward a predictive assessment of stab-penetration forces 

    Destrade, Michel (Lippincott, Williams & Wilkins, 2015-09)
    Collaborative research between the disciplines of forensic pathology and biomechanics was undertaken to investigate the hyperelastic properties of human skin, to determine the force required for sharp instrument penetration ...
  • Uniform transmural strain in pre-stressed arteries occurs at physiological pressure 

    Destrade, Michel; Liu, Yi; Murphy, Jeremiah G.; Kassab, Ghassan S. (Elsevier, 2012-06-21)
    Residual deformation (strain) exists in arterial vessels, and has been previously proposed to induce homogeneous transmural strain distribution. In this work, we present analytical formulations that predict the existence ...
  • 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 ...
  • 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 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 ...
