    • Fine tuning the electro-mechanical response of dielectric elastomers 

      Zurlo, Giuseppe; Destrade, Michel; Lu, Tongqing (AIP Publishing, 2018-10-16)
      We propose a protocol to model accurately the electromechanical behavior of dielectric elastomer membranes using experimental data of stress-stretch and voltage-stretch tests. We show how the relationship between electric ...
    • 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 ...
    • 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 ...
    • Prescribing patterns in growing tubular soft matter by initial residual stress 

      Du, Yangkun; Lü, Chaofeng; Liu, Congshan; Han, Zilong; Li, Jian; Chen, Weiqiu; Qu, Shaoxing; Destrade, Michel (Royal Society of Chemistry, 2019-10-02)
      Initial residual stress is omnipresent in biological tissues and soft matter, and can affect growth-induced pattern selection significantly. Here we demonstrate this effect experimentally by letting soft tubes grow in 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 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 ...
