Design 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 ...
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
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hard-magnetic soft materials, which exhibit finite deformation under magnetic loading, have emerged as a promising class of soft active materials for the development of phononic structures with tunable elastic wave band ...
Nonlinear Oscillations of Particle-Reinforced Electro-Magneto-Viscoelastomer Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents the dynamic modeling and analysis of a particle-reinforced and pre-stressed electro-magneto-viscoelastic plate actuator. The actuator belongs to a smart actuator category and is made of an electro-magneto-active ...
Electromechanical Instability of Dielectric Elastomer Actuators With Active and Inactive Electric Regions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electrically driven dielectric elastomers (DEs) suffer from an electromechanical instability (EMI) when the applied potential difference reaches a critical value. A majority of the past investigations address the mechanics ...
