    • 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 ...
    • 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 ...
