    • Finite bending and pattern evolution of the associated instability for a dielectric elastomer slab 

      Su, Yipin; Wu, Bin; Chen, Weiqiu; Destrade, Michel (Elsevier, 2018-09-21)
      We investigate the finite bending and the associated bending instability of an incompressible dielectric slab subject to a combination of applied voltage and axial compression, using nonlinear electro-elasticity theory and ...
    • Selection shapes synonymous stop codon use in mammals 

      Seoighe, Cathal; Kiniry, Stephen J.; Peters, Andrew; Baranov, Pavel V.; Yang, Haixuan (Springer (part of Springer Nature), 2020-07-02)
      Phylogenetic models of the evolution of protein-coding sequences can provide insights into the selection pressures that have shaped them. In the application of these models synonymous nucleotide substitutions, which do not ...
    • Stability analysis of charge-controlled soft dielectric plates 

      Conroy Broderick, Hannah; Righi, Michele; Destrade, Michel; Ogden, Ray W. (Elsevier, 2020-04-06)
      We examine the stability of a soft dielectric plate deformed by the coupled effects of a mechanical pre-stress applied on its lateral faces and an electric field applied through its thickness under charge control. The ...
    • Tuning the pull-in instability of soft dielectric elastomers through loading protocols 

      Su, Y.P.; Chen, W.Q.; Destrade, Michel (Elsevier, 2019-03-22)
      Pull-in (or electro-mechanical) instability occurs when a drastic decrease in the thickness of a dielectric elastomer results in electrical breakdown, which limits the applications of dielectric devices. Here we derive the ...
    • Wrinkles and creases in the bending, unbending and eversion of soft sectors 

      Sigaeva, Taisiya; Mangan, Robert; Vergori, Luigi; Destrade, Michel; Sudak, Les (The Royal Society, 2018-03-23)
      We study what is clearly one of the most common modes of deformation found in nature, science and engineering, namely the large elastic bending of curved structures, as well as its inverse, unbending, which can be brought ...
    • Wrinkles in soft dielectric plates 

      Su, Yipin; Conroy Broderick, Hannah; Chen, Weiqiu; Destrade, Michel (Elsevier, 2018-07-04)
      We show that a smooth giant voltage actuation of soft dielectric plates is not easily obtained in practice. In principle one can exploit, through pre-deformation, the snap-through behavior of their loading curve to deliver ...
