    • Incremental equations for soft fibrous materials 

      Destrade, Michel (Springer, 2015)
      The general theory of nonlinear anisotropic elasticity is extended to describe small-amplitude motions and static deformations that can be superimposed on large pre-strains of fibre-reinforced solids. The linearised ...

    • Incremental magnetoelastic deformations, with application to surface instability 

      Destrade, Michel (Springer, 2008-01)
      In this paper the equations governing the deformations of infinitesimal (incremental) disturbances superimposed on finite static deformation fields involving magnetic and elastic interactions are presented. The coupling ...

    • An inductive approach to Coxeter arrangements and Solomon's descent algebra 

      Dolan, J. Matthew; Pfeiffer, Götz; Röhrle, Gerhard (Springer Verlag, 2012-07-20)
      In our recent paper (Douglass et al. arXiv: 1101.2075 (2011)), we claimed that both the group algebra of a finite Coxeter group W as well as the Orlik-Solomon algebra of W can be decomposed into a sum of induced one-dimensional ...

    • Influence of initial residual stress on growth and pattern creation for a layered aorta 

      Du, Yangkun; Lü, Chaofeng; Destrade, Michel; Chen, Weiqiu (Nature Research, 2019-06-03)
      Residual stress is ubiquitous and indispensable in most biological and artificial materials, where it sustains and optimizes many biological and functional mechanisms. The theory of volume growth, starting from a stress-free ...

    • Influence of preservation temperature on the measured mechanical properties of brain tissue 

      Rashid, Badar; Destrade, Michel; Gilchrist, Michael D. (Elsevier, 2013-04-26)
      The large variability in experimentally measured mechanical properties of brain tissue is due to many factors including heterogeneity, anisotropy, age dependence and post-mortem time. Moreover, differences in test protocols ...

    • Inhomogeneous "longitudinal" circularly-polarized plane waves in anisotropic elastic crystals 

      Destrade, Michel (S. Hirzel verlag, Ingenta Connect, 2006)
      Conditions on the elastic stiffnesses of anisotropic crystals are derived such that circularly polarized longitudinal inhomogeneous plane waves with an isotropic slowness bivector may propagate for any given direction of ...

    • Inhomogeneous "longitudinal" plane waves in a deformed elastic material 

      Destrade, Michel (Springer, 2005-01)
      By definition, a homogeneous isotropic compressible Hadamard material has the property that an infinitesimal longitudinal homogeneous plane wave may propagate in every direction when the material is maintained in a state ...

    • Inhomogeneous deformation of brain tissue during tension tests 

      Destrade, Michel; Gilchrist, Michael (Elsevier, 2012)
      Mechanical characterization of brain tissue has been investigated extensively by various research groups over the past 50 years. These properties are particularly important for modeling Traumatic Brain Injury (TBI). ...

    • Inhomogeneous shear of orthotropic incompressible non-linearly elastic solids: Singular solutions and biomechanical interpretation 

      Destrade, Michel (Elsevier, 2009)
      We present a detailed study of rectilinear shear deformation in the framework of orthotropic nonlinear elasticity, under Dirichlet and mixed-boundary conditions. We take a slab made of a soft matrix, reinforced with two ...

    • Initial stress symmetry and its applications in elasticity 

      Gower, Artur Lewis; Destrade, Michel (The Royal Society, 2015-10-28)
      An initial stress within a solid can arise to support external loads or from processes such as thermal expansion in inert matter or growth and remodelling in living materials. For this reason, it is useful to develop a ...

    • Initial stresses in elastic solids: Constitutive laws and acoustoelasticity 

      Destrade, Michel (2011)
      On the basis of the nonlinear theory of elasticity, the general constitutive equation for an isotropic hyperelastic solid in the presence of initial stress is derived. This derivation involves invariants that couple the ...

    • Instabilities in elastomers and soft tissues 

      Destrade, Michel (Oxford Journals, 2006-09-15)
      Biological soft tissues exhibit elastic properties that can be dramatically different from rubber-type materials (elastomers). To gain a better understanding of the role of constitutive relationships in determining material ...

    • Instability-induced pattern formations in soft magnetoactive composites 

      Goshkoderia, Artemii; Chen, Vincent; Li, Jian; Juhl, Abigail; Buskohl, Philip; Rudykh, Stephan (American Physical Society, 2020-04-14)
      Elastic instabilities can trigger dramatic microstructure transformations giving rise to unusual behavior in soft matter. Motivated by this phenomenon, we study instability-induced pattern formations in soft magnetoactive ...

    • The integral homology of PSL(2) of imaginary quadratic integers with nontrivial class group 

      Rahm, Alexander D. (2011)
      We show that a cellular complex defined by Flöge allows us to determine the integral homology of the Bianchi groups PSL(2)(O[-m]), where O[-m] is the ring of integers of an imaginary quadratic number field Q [square root ...

    • Interface waves in misoriented pre-stressed incompressible elastic solids 

      Destrade, Michel (Oxford Journals, 2004-12-17)
      Some relationships, fundamental to the resolution of interface wave problems, are presented. These equations allow for the derivation of explicit secular equations for problems involving waves localized near the plane ...

    • Interface waves in pre-stressed incompressible solids 

      Destrade, Michel (Springer, 2007)
      We study incremental wave propagation for what is seemingly the simplest boundary value problem, namely that constitued by the plane interface of a semi-infinite solid. With a view to model loaded elastomers and soft ...

    • Introduction to the special issue on stability under finite deformation 

      Destrade, Michel; Saccomandi, Giuseppe (Oxford University Press, 2010)
      In the botanical gardens of Grenoble, France, there is small bridge, just a few metres long, made of pre-stressed concrete. The bridge dates back to 1855 and is thought to be the oldest manufactured pre-stressed structure ...

    • John Todd and the development of modern numerical analysis 

      Niall Madden (2012)
      The purpose of this article is to mark the centenary of the birth of John Todd, a pioneer in the fields of numerical analysis and computational science. A brief account is given of his early life and career, and that of ...

    • Large acoustoelastic effect 

      Destrade, Michel (Elsevier, 2012-03)
      Classical acoustoelasticity couples small-amplitude elastic wave propagation to an infinitesimal pre-deformation, in order to reveal and evaluate non-destructively third-order elasticity constants. Here, we see that ...

    • Large amplitude Love waves 

      Destrade, Michel (Oxford Journals, 2008-04-22)
      In the context of the finite elasticity theory, we consider a model for compressible solids called 'compressible neo-Hookean material'. We show how finite-amplitude inhomogeneous plane wave solutions and finite-amplitude ...
