Actively controllable topological phase transition in phononic beam systems
(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) ...
Stability analysis of charge-controlled soft dielectric plates
(Elsevier, 2020-04-06)
We examine the stability of a soft dielectric plate deformed by the coupled effects of a mechanical pre-stress applied on its lateral faces and an electric field applied through its thickness under charge control. The ...
Stability analysis of charge-controlled soft dielectric plates
(Elsevier, 2020-04-06)
We examine the stability of a soft dielectric plate deformed by the coupled effects of a mechanical pre-stress applied on its lateral faces and an electric field applied through its thickness under charge control. The ...
Proton resonance frequency shift thermometry: A review of modern clinical practices
(Wiley, 2020-11-20)
Magnetic resonance imaging (MRI) has become a popular modality in guiding minimally invasive thermal therapies, due to its advanced, nonionizing, imaging capabilities and its ability to record changes in temperature. A ...
The effect of an exterior electric field on the instability of dielectric plates
(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-elastic Lamb waves in dielectric plates
(Elsevier, 2020-05-20)
We study the propagation of Lamb waves in soft dielectric plates subject to mechanical and electrical loadings and find the explicit expressions for the dispersion equations in the cases of neo-Hookean and Gent dielectrics. ...
Electrostatically tunable axisymmetric vibrations of soft electro-active tubes
(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 ...
The Poynting effect
(American Association of Physics Teachers, 2020-11-19)
Intuition suggests that twisting a cylinder will shorten it, but here it is shown that for a cylinder of an incompressible material, like rubber, twisting will always produce elongation.
Nonlinear response and axisymmetric wave propagation in functionally graded soft electro-active tubes
(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 ...
Electro-mechanically guided growth and patterns
(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 ...
