Free-Locomotion of Underwater Vehicles Actuated by Ionic Polymer Metal Composites
In this paper, we develop a modeling framework for studying free-locomotion of biomimetic underwater vehicles propelled by vibrating ionic polymer metal composites (IPMCs). The motion of the vehicleExpand

Low frequency and large amplitude oscillations of cantilevers in viscous fluids
We study nonlinear vibrations of cantilever beams oscillating in viscous fluids. A handleable expression for the inertial and damping loads due to the encompassing fluid is proposed. We expand on theExpand
