Abstract: Two types of tubular dielectric elastomers (DE) torsional actuators are studied in this work, which are, respectively, reinforced by a family and two families of helical inextensible fibers. When subject to a radial electric ...

Abstract: This paper investigates the dispersion behavior of elastic wave propagation in hierarchical honeycombs using the finite element method in conjunction with the Bloch's theorem. The hierarchical honeycomb is constructed by ...

Abstract: Metastructures can be designed to exhibit extraordinary properties and thus are widely applicable in various fields, such as vibration suppression, wave control, and energy harvesting. In the present work, a dynamic ...
