Harmonically exited nonlinear vibration of heated functionally graded Plates integrated with piezoelectric composite actuator
Journal of Intelligent Material Systems and Structures, 2015Co-Authors: M.S. Aravinda Kumar, Satyajit Panda, D ChakrabortyAbstract:© The Author(s) 2014. A nonlinear frequency response analysis of a smart functionally graded Plate operating under a heated substrate Plate Surface is presented. The analysis is mainly for investigating the effect of temperature on the harmonically exited nonlinear vibration characteristics of smart functionally graded Plates and also on the corresponding control authority of piezoelectric fiber-reinforced composite actuator bonded to the substrate Plate Surface. A negative velocity feedback control strategy is utilized so as to achieve smart damping. The temperature-dependent material properties of the ceramic metal-based functionally graded Plate are graded in the thickness direction. Based on the von Karman nonlinear strain-displacement relations and assuming periodic motion, a nonlinear dynamic incremental finite element model of the overall smart functionally graded Plate is developed. An arc-length extrapolation technique with a new strategy for determining the arc length is used for numerical solutions. The analysis reveals significant effects of temperature and metal volume fraction in substrate on the structural dynamic behavior of the overall Plate. The analysis also reveals the effects of temperature, metal volume fraction in substrate, fiber volume fraction in piezoelectric fiber-reinforced composite, and fiber orientation in piezoelectric fiber-reinforced composite on the smart damping. For using the piezoelectric fiber-reinforced composite actuator in the form of a patch, its optimal location and size are numerically determined.

Piezo-viscoelastically damped nonlinear frequency response of functionally graded Plates with a heated Plate-Surface:
Journal of Vibration and Control, 2014Co-Authors: A. K. MS, Satyajit Panda, D ChakrabortyAbstract:A geometrically nonlinear frequency-domain analysis of functionally graded Plates integrated with an active constrained layer damping (ACLD) arrangement is performed by developing an incremental nonlinear closed-loop dynamic finite element model of the overall Plate. The active constraining layer is made of piezoelectric fiber reinforced composite (PFRC) and a heated substrate-Plate Surface is considered. The analysis is mainly for investigating the effect of temperature on the nonlinear vibration characteristics of the overall Plate in the frequency domain and also, on the corresponding control authority of the PFRC constraining layer. A negative velocity feedback control strategy is utilized to achieve active damping. The temperature dependent material properties of the substrate Plate are graded in the thickness direction according to a power law, and expressed in terms of the power law exponent and the constituent material (metal and ceramic) properties. Using the Golla-Hughes-McTavish method for mode...

An arc-length extrapolation solution technique is used in combination with a new strategy for determination of incremental arc-length. The numerical illustrations show a potential use of PFRC actuator in the ACLD arrangement and suggest an optimal thickness of viscoelastic layer for more effective use of PFRC. The analysis reveals the significant effects of initial thermal bending of the overall smart Plate on its nonlinear dynamic behavior in the frequency domain. The effects of temperature, metal-volume fraction in substrate, fiber volume fraction in PFRC and the fiber orientation angle in the PFRC on the control authority of the ACLD layer are presented. For the use of the ACLD layer in the form of a patch, a new numerical strategy for determining its optimal location and optimal size for effective control is presented.

Identification models for transient heat transfer on a flat plat
Experimental Thermal and Fluid Science, 2007Co-Authors: Ali Grine, Didier Saury, Jean-yves Desmons, Souad HarmandAbstract:This paper presents new methods for identifying the convective heat transfer on a flat Plate using analytical models bases on the Green functions theory. The air flows over a flat Plate heated by applying a controlled and transient radiative heat flux to one of its Surfaces. On the opposite Surface, the Plate is cooled by another air flow. The temperature profile of the Plate Surface is determined with an infrared camera when the Plate is exposed to the controlled heat flux. Green functions are used to determine analytical solutions for the heat flux equation in the Plate. These analytical solutions allow the transient convective heat transfer to be identified.
