RISDesign of a Command-Shaping Scheme for Mitigating Residual Vibrations in Dielectric Elastomer Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dielectric elastomers (DEs) are a class of highly deformable electroactive polymers (EAPs) employed for electromechanical transduction technology. When electrostatically actuated dielectric elastomer actuators (DEAs) are ...
Revisiting the Lattice Boltzmann Method Through a Nonequilibrium Thermodynamics Perspective
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we incorporate a nonequilibrium thermodynamics perspective that is consistent with the Onsager reciprocity principle into the lattice Boltzmann framework to propose a novel regularized lattice Boltzmann ...
Viscoelastic Effects on the Nonlinear Oscillations of Hard-Magnetic Soft Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hard-magnetic soft materials (HMSMs) belong to the magnetoactive category of smart polymers that undergo large actuation strain under an externally applied magnetic field and can sustain a high residual magnetic flux ...
Topology Optimization of Hard-Magnetic Soft Phononic Structures for Wide Magnetically Tunable Band Gaps
