“…Since the location of the maximum deflection is a function of the PZT location, both ( , ) ξ θ and 0 0 ( , ) ξ θ should be considered as variables to determine max w . Yang and Zhang (2006) [10] have studied the optimal placement of PZT actuator on rectangular plates in term of maximum excitation. The shell vibration solution in Eq.…”

In this paper, a simply supported thin cylindrical shell segment excited by a pair of collocated PZT actuators is studied. A closed-form solution has been obtained to describe the radial vibration of the shell. Based on this solution, optimal placement of the pair of PZT actuators in terms of maximizing the vibration of shell is discussed and numerically verified. It is found that the pattern of the optimal locations of the PZT actuators can be represented by a simple function, namely, the position mode function (PMF) or their combinations.

This work is aimed at the active vibration control of a flexible structures using piezoelectric material. A simple supported plate structure, which is supported at two opposite ends, is taken as the flexible structure with piezoelectric materials as sensors and actuators. Sensors and actuators, which are square in shapes, are embedded to the parent structure. The active controller was designed to control first three modes of vibration of plate. First, the analysis for the transient vibrations in a simple supported plate structure was performed which was followed by the analysis of the same simple supported plate structure when embedded upon with a pair of sensor and actuator. The plate was discretised into several small rectangular elements (6X6, 7X7… 11X11) of identical size in order to assign the different locations to sensors and actuators, which were assumed to be of the exact shape of the discretized plate elements. Further a LQR controller is applied for attenuating the global structural vibration. Settling time for each different location of piezoelectric patch location was observed which was then followed by an interpretation for the optimal location for piezoelectric patch for maximizing the vibration control. The model designed for study was duly verified with the results from past literature and an agreement between the both was observed.

a b s t r a c tThis paper reports the result of an investigation into the effect of electric and mechanical loads on the morphological evolution of a void in piezoelectric materials based on a model for the morphological evolution of a void, the thermodynamics potential and energy principle. Thus, the path and the bifurcation condition of the morphological evolution of the void in piezoelectric materials are described, which gives some insight into the reliability of piezoelectric films under electric and mechanical loads.
