  • 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 ...
  • Cell complexes database for the Bianchi groups 

    Rahm, Alexander D. (NUI Galway, 2016-05-18)
    This is a database of quotients by Bianchi groups of two-dimensional cellular equivariant retracts of Hyperbolic three-space. The Bianchi groups SL(2, A), with A the ring of integers in the imaginary quadratic number field ...
  • A census of human soluble protein complexes 

    Yang, Haixuan (Elsevier, 2012-08-11)
    Cellular processes often depend on stable physical associations between proteins. Despite recent progress, knowledge of the composition of human protein complexes remains limited. To close this gap, we applied an integrative ...
  • 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 ...
  • Characteristic classes of complexified bundles 

    Rahm, Alexander D. (Summer School in Algebraic Topology: Sheaf theoretic methods in the theory of characteristic classes, 2007)
    We examine the topological characteristic cohomology classes of complexified vector bundles . In particular, all the classes coming from real vector bundles are computed. We use characteristic classes with the ax-ioms of ...
  • Circularly-polarized plane waves in a deformed Hadamard material 

    Destrade, Michel (Elsevier, 2001-10-31)
    Small-amplitude inhomogeneous plane waves propagating in any direction in a homogeneously deformed Hadamard material are considered. Conditions for circular polarization are established. The analysis relies on the use of ...
  • (Co)homologies et K-théorie de groupes de Bianchi par des modèles géométriques calculatoires 

    Rahm, Alexander D. (Université de Grenoble / Universität Göttingen, 2010-10-15)
    Cette thèse consiste d'une étude de la géométrie d'une certaine classe de groupes arithmétiques, à travers d'une action propre sur un espace contractile. Nous calculons explicitement leur homologie de groupe, et leur ...
  • 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 ...
  • Compact travelling waves in viscoelastic solids 

    Destrade, Michel (IOP Science, 2009-09-02)
    We introduce a model for nonlinear viscoelastic solids, for which travelling shear waves with compact support are possible. Using analytical and numerical methods, we investigate the general case of this model, and an ...
  • Complexifiable characteristic classes 

    Rahm, Alexander D. (Springer, 2014-01)
    We examine the topological characteristic cohomology classes of complexified vector bundles. In particular, all the classes coming from the real vector bundles underlying the complexification are determined.
  • Complexifiable characteristic classes 

    Rahm, Alexander D. (2013)
  • Compression instabilities of tissues with localized strain softening. 

    Destrade, Michel (World Scientific Publishing Company, 2010-09-27)
    The stress-strain relationship of biological soft tissues affected by Marfan's syndrome is believed to be nonconvex. More specifically, Haughton and Merodio recently proposed a strain energy density leading to localized ...
  • Computational Selection of Transcriptomics Experiments Improves Guilt-by-Association Analyses 

    Yang, Haixuan (PLos ONE, 2012-08-07)
    The Guilt-by-Association (GBA) principle, according to which genes with similar expression profiles are functionally associated, is widely applied for functional analyses using large heterogeneous collections of transcriptomics ...
  • Creep, recovery, and waves in a nonlinear fiber-reinforced viscoelastic solid 

    Destrade, Michel (Society for Industrial and Applied Mathematics, 2007-10-10)
    We present a constitutive model capturing some of the experimentally observed features of soft biological tissues: nonlinear viscoelasticity, nonlinear elastic anisotropy, and nonlinear viscous anisotropy. For this model ...
  • Deficiencies in numerical models of anisotropic nonlinearly elastic materials 

    Ní Annaidh, Aisling; Destrade, Michel; Gilchrist, M.; Murphy, J.G. (Springer, 2013-08)
    Incompressible nonlinearly hyperelastic materials are rarely simulated in finite element numerical experiments as being perfectly incompressible because of the numerical difficulties associated with globally satisfying ...
  • Determination of friction coefficient in unconfined compression of brain tissue 

    Rashid, Badar; Destrade, Michel; Gilchrist, Michael (Elsevier, 2012-10)
    Unconfined compression tests are more convenient to perform on cylindrical samples of brain tissue than tensile tests in order to estimate mechanical properties of the brain tissue because they allow for homogeneous ...
  • Differences in tension and compression in the nonlinearly elastic bending of beams 

    Destrade, Michel (Texas Digital Library, 2009-02)
    The classical flexure problem of non-linear incompressible elasticity is revisited for elastic materials whose mechanical response is different in tension and compression - the so-called bimodular materials. The flexure ...
  • Diffusionrank: a possible penicillin for web spamming 

    Yang, Haixuan (2007)
    While the PageRank algorithm has proven to be very effective for ranking Web pages, the rank scores of Web pages can be manipulated. To handle the manipulation problem and to cast a new insight on the Web structure, we ...
  • 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 ...

    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 ...
