Closed Loop Finite Element Modeling of Piezoelectric Smart Structures

Finite Element Analysis of Functionally Graded‎ ‎Piezoelectric Beams

In this paper‎, ‎the static bending‎, ‎free vibration‎, ‎and dynamic response of functionally graded‎ ‎piezoelectric beams have been carried out by finite element method‎‎under different sets of mechanical‎, ‎thermal‎, ‎and electrical‎ ‎loadings‎. ‎The beam with functionally graded piezoelectric material‎ ‎(FGPM) is assumed to be graded across the thickness with a simple‎ ‎power law distributio...

Closed-Loop Deployable Structures

This paper is concerned with a novel kind of deployable structures that form closed loops that fold into a bundle of bars using simple hinges. These structures, first envisaged by Dr J.M. Hedgepeth, have potential applications for ultra-lightweight solar arrays, solar sails, and radar structures. A systematic study of the kinematics of closed-loop structures is carried out, and a scheme for sim...

Finite element modeling of thermoviscous acoustics in closed cavities

Covariance Control Using Closed Loop Modeling for Structures 1

This paper presents a low order controller design method, using closed loop modeling plus covariance control, with application to the benchmark problem in structural control for the active mass drive system at the University of Notre Dame [1]. This method nds a satisfactory controller by iterating between closed loop modeling and covariance control. The closed loop modeling implies that the mod...

study of behavior of reinforced concrete beams with smart rebars using finite element modeling

in this paper the response of cantilevered reinforced concrete (rc) beams with smart rebars under static lateral loading has been numerically studied, using finite element method. the material used in this study is superelasticshape memory alloys (se smas) which contains nickel and titanium elements. the se sma is a unique alloy that has the ability to undergo large deformations and return to t...
