Mixing at Low Reynolds Numbers by Vibrating Cantilevered Ionic Polymers
… a quantitative mixing metric shows that using cantilevered polymers create increases mixing potential in the flow for some actuation cases. Although these differences are present, they do not appear consistently in the results. However, only a partial set of flow information was obtained from …

Fluid-structure interaction of a cantilevered plate in supersonic separated flow
… (UIUC) have focused on the FSI of a cantilevered plate geometry in Mach 2 flow. The geometry of interest, representative of a compliant control surface, consists of an overhanging plate that extends past the edge of a backward-facing step to create a separated region in the supersonic …

The control of flexible structure vibrations using a cantilevered adaptive truss
… control of flexible structure vibrations using a cantilevered adaptive truss. A specific six-actuator, octahedral-octahedral truss effects the control of different flexible structures. These structures could represent space structures or robotic manipulators or a variety of other flexible …

Development of Residual Stress Measurement for Concrete Pavements through Cantilevered Beam Testing
… rings to create a similar stress relaxation in cantilevered concrete beams. The cantilevered beams were used to create a known and moderately-uniform stress state in the specimens. Testing at the University of Illinois continued the use of core rings and cantilevered beams and also introduced a …

Three dimensional topology and structural differences in the turbulent wake of cantilevered square and circular cylinders protruding thin boundary layers
… study is conducted of the flow around cantilevered circular and square-section cylinders to investigate the effects of the cylinder geometry and the boundary layer state on the wake structures and flow topology. Detailed velocimetry results are presented in the wake of circular and …

Position control and vibration suppression of a flexible beam-like structure cantilevered from a rotary actuator within a gravitational field
An analytical and experimental investigation into the position and vibration control of beam-like structures within a gravity field using only root actuation was performed. Two methods were used to linearize the system's equations of motion. This, in turn, allowed for the use of powerful Modern …

Theoretical analysis and design of a double-clamped microchannel resonator
… Sungmin Son's theoretical analysis of a cantilevered microchannel beam that is fixed at both ends. The current design used in lab is a traditional cantilevered beam and has been successful in producing results in the detection of biological molecules. This new design is an experiment on …

THE DETERMINATION OF DRAG AND LIFT FORCES OF A RIGID BEAM LOCATED WITHIN A TURBULENT BOINDARY LAYER BY MEANS OF LARGE EDDY SIMULATION MODELING
… of energy harvesters. In such study, a flexible cantilevered beam was fitted with a cylindrical prism at the free end and placed within a uniform flow field. Due to the vortex shedding generated by the prism (e.g. Von Karman vortices) the beam was found to oscillate about the undisturbed …

Vibration control and design of composite cantilevers taking into account structural uncertainties and damage
… coupling and the warping restraint on the cantilevered structure are also considered. As passive techniques of vibration control, structural tailoring and optimization are implemented. To deal with structural uncertainties, a probabilistic discretization technique for the governing system …

Characterization, Modeling, and Control of Ionic Polymer Transducers
… polymer sensors and actuators, when used in the cantilevered bender configuration, are discussed and compared to piezoceramic and piezo polymer cantilevered benders. The energy density of all three actuators are within an order of magnitude of one another, with peak values of approximately …

The theory of anisotropic thin- and thick-walled closed cross-section beams with coupled elastic deformations
… analysis using ABAQUS has been performed for a cantilevered circular thick section beam under pure tip torque and a cantilevered thick-walled box beam under tip shear or torsional loading in an effort to validate the present theory for thick-walled beams. Again, the correlation between the …

Characterization of Bending Magnetostriction in Iron-Gallium Alloys for Nanowire Sensor Applications
… calls for incorporating Galfenol nanowires cantilevered from a membrane and attached to a conventional magnetic field sensor. As the wires deflect in response to acoustic, airflow, or tactile excitation, the resultant bending stresses induce changes in magnetization that due to the scale of …

Large Deflection Inextensible Beams and Plates and their Responses to Nonconservative Forces: Theory and Computations
… boundary conditions of the beam are explored: cantilevered and free-free. For a plate, the cantilevered boundary condition is considered. In these conditions, the nonlinearity stems from the structure's large curvature rather than from stretching. Therefore, this model makes use of the …

Performance and Evaluation of a Variable-Speed Darrieus Wind Turbine
… the Darrieus are the . cable tie-down system and cantilevered system. The cable tie-down support method uses several guy cables which are connected from the ground to the top of the turbine rotor. The cantilevered system, which supports the rotor only at the base, is simpler since there is no need …
