  • Brillouin scattering study on the single-crystal elastic properties of natrolite and analcime zeolites 

    Sanchez-Valle, Carmen; Sinogeikin, Stanislav V.; Lethbridge, Zoe A. D.; Walton, Richard I.; Smith, Christopher W.; Evans, Kenneth E.; Bass, Jay D. (American Institute of Physics, 2005)
    The Brillouin light-scattering technique was used to investigate the single-crystal elastic properties of two aluminosilicate zeolites, natrolite (NAT) and analcime (ANA), at ambient conditions. An inversion of the acoustic ...
  • Effect of heterogeneity on the elastic properties of auxetic materials 

    Gaspar, N.; Smith, Christopher W.; Evans, Kenneth E. (American Institute of Physics, 2003)
    Auxetic materials are gaining practical interest for their unusual and sometimes extreme mechanical response. The process of modeling these materials so far has highlighted a number of microstructural properties that are ...
  • ElAM: A computer program for the analysis and representation of anisotropic elastic properties 

    Marmier, Arnaud; Lethbridge, Zoe A. D.; Walton, Richard I.; Smith, Christopher W.; Parker, Stephen C.; Evans, Kenneth E. (Elsevier, 2010)
    The continuum theory of elasticity has been used for more than a century and has applications in many fields of science and engineering. It is very robust, well understood and mathematically elegant. In the isotropic case ...
  • Elastic anisotropy and extreme Poisson's ratios in single crystals 

    Lethbridge, Zoe A. D.; Walton, Richard I.; Marmier, Arnaud; Smith, Christopher W.; Evans, Kenneth E. (Elsevier, 2010)
    The relationship between elastic anisotropy and extreme Poisson’s ratio behaviour (either positive or negative) in single-crystalline materials has been investigated using experimentally determined single-crystal elastic ...
  • Manufacture and Characterisation of a Novel, Low Modulus, Negative Poisson’s Ratio Composite 

    Miller, W.; Hook, P.B.; Smith, Christopher W.; Wang, X.; Evans, Kenneth E. (Elsevier, 2009)
    Relatively few negative Poisson’s ratio (auxetic) composites have been manufactured and characterised and none with inherently auxetic phases [Milton G. J. Mech. Phys. Solids 1992;40:1105–37]. This paper presents the use ...
  • Multi-objective optimisation of viscoelastic damping inserts in honeycomb sandwich structures 

    Aumjaud, Pierre; Fieldsend, Jonathan E.; Boucher, Marc-Antoine; Evans, Kenneth E.; Smith, Christopher W. (Elsevier, 2015-11-15)
    The Double-Shear Lap Joint (DSLJ) is a novel damping insert sited internally within a structure which is particularly well suited for lightweight sandwich structures with internal voids, such as honeycomb core sandwich ...
  • A novel viscoelastic damping treatment for honeycomb sandwich structures 

    Aumjaud, Pierre; Smith, Christopher W.; Evans, Kenneth E. (Elsevier, 2015-01-01)
    Constrained layer dampers (CLD) are in widespread use for passive vibration damping, in applications including aerospace structures which are often lightweight. The location and dimensions of CLD devices on structures has ...
  • On the effective strain tensor in heterogeneous materials 

    Berger, M.A.; Evans, Kenneth E; Smith, Christopher W. (SAGE Publications, 2014-02-09)
    This paper considers effective strain tensors within the context of linear elastic equilibrium theory. The elastic properties of structured materials are often averaged over subvolumes of various scales inside the material. ...
  • Optimised location and orientation of passive viscoelastic dampers for lightweight sandwich structures 

    Aumjaud, Pierre; Smith, Christopher W.; Fieldsend, Jonathan E.; Evans, Kenneth E. (International Conference on Electrical Machines (ICEM), 2014)
    The recently developed Double Shear Lap-Joint (DSLJ) damper technology is a new device which can be placed internally within lightweight structures. This work considers the optimal location and orientation of DSLJ dampers ...
  • Simulated Optimisation of Disordered Structures with negative Poisson’s ratios 

    Horrigan, E.J.; Smith, Christopher W.; Scarpa, F.; Gaspar, N.; Javadi, Akbar A.; Berger, M.A.; Evans, Kenneth E. (Elsevier, 2009)
    Two-dimensional regular theoretical units that give a negative Poisson’s ratio (NPR) are well documented and well understood. Predicted mechanical properties resulting from these models are reasonably accurate in two ...
