    • 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 ...
    • Minimal characteristic bisets and finite groups realizing Ruiz-Viruel exotic fusion systems 

      Park, Sejong (Elsevier, 2011)
      Continuing our previous work (Park, 2010) [2], we determine a minimal left characteristic biset X for every exotic fusion system FF on the extraspecial group S of order 73 and exponent 7 discovered by Ruiz and Viruel (2004) ...
    • Mining social networks using heat diffusion processes for marketing candidates selection 

      Yang, Haixuan (ACM, 2008)
      Social Network Marketing techniques employ pre-existing social networks to increase brands or products awareness through word-of-mouth promotion. Full understanding of social network marketing and the potential candidates ...
    • 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, ...
    • Modified multiplicative decomposition model for tissue growth: Beyond the initial stress-free state 

      Du, Yangkun; Lü, Chaofeng; Chen, Weiqiu; Destrade, Michel (Elsevier, 2018-05-19)
      The multiplicative decomposition model is widely employed for predicting residual stresses and morphologies of biological tissues due to growth. However, it relies on the assumption that the tissue is initially in a ...
    • Monstrous and Generalized Moonshine and Permutation Orbifolds 

      Tuite, Michael P. (2008)
      We consider the application of permutation orbifold constructions towards a new possible understanding of the genus zero property in Monstrous and Generalized Moonshine. We describe a theory of twisted Hecke operators in ...
    • Multi-sector approximation method for arteries: the residual stresses of circumferential rings with non-trivial openings 

      Sigaeva, Taisiya; Destrade, Michel; Di Martino, Elena S. (The Royal Society, 2019-07-24)
      The opening angle method is a popular choice in biomechanics to estimate residual stresses in arteries. Experimentally, it means that an artery is cut into rings; then the rings are cut axially or radially allowing them ...
    • 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, ...
    • N=2 and N=4 subalgebras of super vertex operator algebras 

      Tuite, Michael P.; Mason, Geoffrey; Yamskulna, Gaywalee (IOP Publishing, 2018-01-10)
      We develop criteria to decide if an N=2 or N=4 super conformal algebra is a subalgebra of a super vertex operator algebra in general, and of a super lattice theory in particular. We give some specific examples.
    • Non-invasive evaluation of skin tension lines with elastic waves 

      Deroy, Claire; Destrade, Michel; Mc Alinden, Aidan; Ní Annaidh, Aisling (Wiley, 2017-11-20)
      Background: Since their discovery by Karl Langer in the 19th Century, Skin Tension Lines (STLs) have been used by surgeons to decide the location and orientation of an incision. Although these lines are patient-specific, ...
    • Non-principal surface waves in deformed incompressible materials 

      Destrade, Michel (Elsevier, 2005)
      The Stroh formalism is applied to the analysis of infinitesimal surface wave propagation in a statically, finitely and homogeneously deformed isotropic half-space. The free surface is assumed to coincide with one of the ...
    • Noninvasive measurement of local stress inside soft materials with programmed shear waves 

      Zhang, Zhaoyi; Li, Guo-Yang; Jiang, Yuxuan; Zheng, Yang; Gower, Artur L.; Destrade, Michel; Cao, Yanping (American Association for the Advancement of Science, 2023-03-08)
      Mechanical stresses across different length scales play a fundamental role in understanding biological systems¿ functions and engineering soft machines and devices. However, it is challenging to noninvasively probe local ...
    • Nonlinear elastic vector solitons in hard-magnetic soft mechanical metamaterials 

      Zhang, Quan; Cherkasov, Andrei V.; Xie, Chen; Arora, Nitesh; Rudykh, Stephan (Elsevier, 2023-07-14)
      We propose a design of a metamaterial for magnetically tunable propagation of nonlinear vector solitary waves. The metamaterial consists of a periodic array of units of hard-magnetic inclusion embedded in a soft matrix. ...
    • Nonlinear Euler buckling 

      Goriely, Alain; Vandiver, Rebecca; Destrade, Michel (Royal Society Publishing, 2008-11)
      The buckling of hyperelastic incompressible cylindrical tubes of arbitrary length and thickness under compressive axial load is considered within the framework of nonlinear elasticity. Analytical and numerical methods for ...
    • Nonlinear response and axisymmetric wave propagation in functionally graded soft electro-active tubes 

      Wu, Bin; Destrade, Michel; Chen, Weiqiu (Elsevier, 2020-10-02)
      Soft electro-active (SEA) materials can be designed and manufactured with gradients in their material properties, to modify and potentially improve their mechanical response in service. Here, we investigate the nonlinear ...
    • Nonlinear transverse waves in deformed dispersive solids 

      Destrade, Michel (Elsevier, 2008)
      We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) properties of a hyperelastic dispersive ...
    • A note on element centralizers in finite Coxeter groups 

      Konvalinka, Matjaž; Pfeiffer, Götz; Röver, Claas E. (De Gruyter, 2011-08-29)
      The normalizer N-W(W-J) of a standard parabolic subgroup W-J of a finite Coxeter group W splits over the parabolic subgroup with complement N-J consisting of certain minimal length coset representatives of W-J in W. In ...
    • 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 ...
    • On a question of Serre 

      Rahm, Alexander D. (2012)
      Consider an imaginary quadratic number field Q(root -m), with m a square-free positive integer, and its ring of integers {O} . The Bianchi groups are the groups SL2{O}. Further consider the Borel-Serre compactification [7] ...
