VIBRATIONS OF THIN PLATE WITH PIEZOELECTRIC ACTUATOR: THEORY AND EXPERIMENTS A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Master of Science Mechanical Engineering by Parikshit Mehta December 2009 Accepted by: Dr. Nader Jalili, Committee Chair Dr. Mohammed Daqaq Dr. Marian Kennedy ABSTRACT Vibrations of flexible structures have been an important engineering study owing to its both deprecating and complimentary traits. These flexible structures are generally modeled as strings, bars, shafts and beams (one dimensional), membranes and plate (two dimensional) or shell (three dimensional). Structures in many engineering applications, such as building floors, aircraft wings, automobile hoods or pressure vessel end-caps, can be modeled as plates. Undesirable vibrations of any of these engineering structures can lead to catastrophic results. It is important to know the fundamental frequencies of these structures in response to simple or complex excitations or boundary conditions. After their discovery in 1880, piezoelectric materials have made their mark in various engineering applications.
