    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 ...

    Influence of initial residual stress on growth and pattern creation for a layered aorta 

    Du, Yangkun; Lü, Chaofeng; Destrade, Michel; Chen, Weiqiu (Nature Research, 2019-06-03)
    Residual stress is ubiquitous and indispensable in most biological and artificial materials, where it sustains and optimizes many biological and functional mechanisms. The theory of volume growth, starting from a stress-free ...

    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 ...

    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 ...

    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 ...

    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 ...

    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 ...

    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 ...

    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 ...
