  • Bending instabilities of soft biological tissues 

    Destrade, Michel; Ní Annaidh, Aisling (Elsevier, 2009-12-15)
    Rubber components and soft biological tissues are often subjected to large bending deformations while 'in service'. The circumferential line elements on the inner face of a bent block can contract up to a certain critical ...
  • 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 ...
  • Bleustein-Gulyaev waves in some functionally graded materials 

    Destrade, Michel (Elsevier, 2006-02-28)
    Functionally Graded Materials are inhomogeneous elastic bodies whose properties vary continuously with space. Hence consider a half-space (x2>0) occupied by a special Functionally Graded Material made of an hexagonal (6 ...
  • The BMR freeness conjecture for the 2-reflection groups 

    Marin, Ivan; Pfeiffer, Götz (American Mathematical Society, 2016-10-12)
    We prove the freeness conjecture of Broue, Malle and Rouquier for the Hecke algebras associated to the primitive complex 2-reflection groups with a single conjugacy class of reflections.
  • 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 ...
  • 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 ...
  • 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 ...
  • Cohomology of Coxeter arrangements and Solomon's descent algebra 

    Douglass, J. Matthew; Pfeiffer, Götz; Röhrle, Gerhard (American Mathematical Society, 2014-06-19)
    We refine a conjecture by Lehrer and Solomon on the structure of the Orlik-Solomon algebra of a finite Coxeter group W and relate it to the descent algebra of W. As a result, we claim that both the group algebra of W 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 ...
  • 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 ...
  • Computations for Coxeter arrangements and Solomon's descent algebra II: Groups of rank five and six 

    Bishop, Marcus; Douglass, J. Matthew; Pfeiffer, Götz; Röhrle, Gerhard (Elsevier, 2013-01-08)
    In recent papers we have refined a conjecture of Lehrer and Solomon expressing the character of a finite Coxeter group W acting on the graded components of its Orlik-Solomon algebra as a sum of characters induced from ...
  • Computations for Coxeter arrangements and Solomon's descent algebra III: Groups of rank seven and eight 

    Bishop, Marcus; Douglass, J. Matthew; Pfeiffer, Götz; Röhrle, Gerhard (Elsevier, 2014-11-06)
    In this paper we extend the computations in parts I and II of this series of papers and complete the proof of a conjecture of Lehrer and Solomon expressing the character of a finite Coxeter group W acting on the p-th graded ...
  • Computations for Coxeter arrangements and Solomon's descent algebra: Groups of rank three and four 

    Bishop, Marcus; Douglass, J. Matthew; Pfeiffer, Götz; Röhrle, Gerhard (Elsevier, 2012-06-03)
    In recent papers we have refined a conjecture of Lehrer and Solomon expressing the characters of a finite Coxeter group W afforded by the homogeneous components of its Orlik-Solomon algebra as sums of characters induced ...
  • Computing the table of marks of a cyclic extension 

    Naughton, L.; Pfeiffer, Götz (American Mathematical Society, 2012-02-24)
    The subgroup pattern of a finite group C is the table of marks of G together with a list of representatives of the conjugacy classes of subgroups of G. In this article we present an algorithm for the computation of the ...
  • 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 ...
