Nonlinear deformation analysis of a dielectric elastomer membrane–spring system
Due to their large strain capability, dielectric elastomers are promising materials for application as transducers in cameras, robots, valves, pumps, energy harvesters, and so on. The dielectric elastomer transducers are based on the deformation of a soft polymer membrane contracting in thickness and expanding in area, induced by the application of a voltage across the two compliant electrodes ...
متن کاملNonlinear electroelastic deformations of dielectric elastomer composites_ I—Ideal elastic dielectrics
This paper puts forth homogenization solutions for the macroscopic elastic dielectric response—under finite deformations and finite electric fields—of ideal elastic dielectric composites with two-phase isotropic particulate microstructures. Specifically, solutions are presented for three classes of microstructures: (i) an isotropic iterative microstructure wherein the particles are infinitely p...
متن کاملNonlinear electroelastic deformations of dielectric elastomer composites_ II — Non-Gaussian elastic dielectrics
This paper presents an analytical framework to construct approximate homogenization solutions for the macroscopic elastic dielectric response — under finite deformations and finite electric fields — of dielectric elastomer composites with two-phase isotropic particulate microstructures. The central idea consists in employing the homogenization solution derived in Part I of this work for ideal e...
متن کاملA numerical method to enhance the accuracy of mass-spring systems for modeling soft tissue deformations.
This technical note presents a numerical corrective technique that allows control of nonlinearity in a mass-spring system (MSS) independent of its spring constants or system topology. The governing equations of MSS in the form of ordinary differential equations or a regular function accompanied by any boundary or initial condition as known constraints, are employed to modify the results. A leas...
متن کاملModelling nonlinear regenerative effects in metal cutting
This paper deals with the nonlinear models of regenerative chatter on machine tools. The limitations and actual problems of the existing theory are summarized. These cause difficulties in industrial applications, like in the design of optimum technological parameters, adaptive control and/or vibration-suppression strategies. An industrial machine-tool vibration case is analysed experimentally a...
