    • Actively controllable topological phase transition in phononic beam systems 

      Zhou, Weijian; Chen, Weiqiu; Destrade, Michel; Lim, C.W. (Elsevier, 2020-05-01)
      Topological insulators, which allow edge or interface waves but forbid bulk waves, have revolutionized our scientific cognition of acoustic/elastic systems. Due to their nontrivial topological characteristics, edge (interface) ...

    • The effect of an exterior electric field on the instability of dielectric plates 

      Su, Yipin; Chen, Weiqiu; Dorfmann, Luis; Destrade, Michel (The Royal Society, 2020-07-29)
      We investigate the theoretical nonlinear response, Hessian stability, and possible wrinkling behaviour of a voltage-activated dielectric plate immersed in a tank filled with silicone oil. Fixed rigid electrodes are placed ...

    • Electro-mechanically guided growth and patterns 

      Du, Yangkun; Su, Yipin; Lü, Chaofeng; Chen, Weiqiu; Destrade, Michel (Elsevier, 2020-07-01)
      Several experiments have demonstrated the existence of an electro-mechanical effect in many biological tissues and hydrogels, and its actual influence on growth, migration, and pattern formation. Here, to model these ...

    • Electrostatically tunable axisymmetric vibrations of soft electro-active tubes 

      Zhu, Fangzhou; Wu, Bin; Destrade, Michel; Chen, Weiqiu (Elsevier, 2020-05-28)
      Due to their unique electromechanical coupling properties, soft electro-active (SEA) resonators are actively tunable, extremely suitable, and practically important for designing the next-generation acoustic and vibration ...

    • 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 ...

    • Magnetic field-induced asymmetric mechanical metamaterials 

      Zhang, Quan; Cherkasov, Andrei V.; Arora, Nitesh; Hu, Gengkai; Rudykh, Stephan (Elsevier, 2023)
      We propose a magnetic field-induced asymmetric mechanical metamaterial. The tunable metamaterial integrates hard-Magnetic Active Elastomers (hMAEs) into the microstructural design combining snap-through, bi-stability, 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 ...

    • 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 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 ...

    • Pattern evolution in bending dielectric-elastomeric bilayers 

      Su, Yipin; Wu, Bin; Chen, Weiqiu; Destrade, Michel (Elsevier, 2019-07-24)
      We propose theoretical and numerical analyses of smart bending deformation of a dielectric-elastic bilayer in response to a voltage, based on the nonlinear theory of electro-elasticity and the associated linearized incremental ...

    • 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 ...
