Report

Nonlinear vibration and stability of a dielectric elastomer balloon based on a strain-stiffening model

Autor: Alibakhshi, Amin, Chen, Weiqiu, Destrade, Michel

Publikováno v: Journal of Elasticity, 153 (2022) 533-548

Limiting chain extensibility is a characteristic that plays a vital role in the stretching of highly elastic materials. The Gent model has been widely used to capture this behaviour, as it performs very well in fitting stress-stretch data in simple t

Tunable topological phase transition in soft Rayleigh beam system with imperfect interfaces

Autor: Feng, Tao, Gan, Letian, Zhao, Shiheng, Chang, Zheng, Li, Siyang, Xue, Yaoting, Yang, Xuxu, Wong, Tuck-Whye, Li, Tiefeng, Chen, Weiqiu

Acoustic metamaterials, particularly the topological insulators, exhibit exceptional wave characteristics that have sparked considerable research interest. The study of imperfect interfaces affect is of significant importance for the modeling of wave

Report

Tunable morphing of electroactive dielectric-elastomer balloons

Autor: Su, Yipin, Riccobelli, Davide, Chen, Yingjie, Chen, Weiqiu, Ciarletta, Pasquale

Designing smart devices with tunable shapes has important applications in industrial manufacture. In this paper, we investigate the nonlinear deformation and the morphological transitions between buckling, necking, and snap-through instabilities of l

Report

Vibrations and waves in soft dielectric elastomer structures

Autor: Zhao, Zinan, Chen, Yingjie, Hu, Xueyan, Bao, Ronghao, Wu, Bin, Chen, Weiqiu

Dielectric elastomers (DEs) are a type of multifunctional materials with salient features that are very attractive in developing soft, lightweight, and small-scale transducers and robotics. This paper reviews the mechanics of soft DE structures, focu

Voltage-controlled topological interface states for bending waves in soft dielectric phononic crystal plates

Autor: Chen, Yingjie, Wu, Bin, Destrade, Michel, Chen, Weiqiu

The operating frequency range of passive topological phononic crystals is generally fixed and narrow, limiting their practical applications. To overcome this difficulty, here we design and investigate a one-dimensional soft dielectric phononic crysta
