Vibration Analysis of Functionally Graded Piezoelectric Actuators

This book presents a detailed study on the vibration analysis of functionally graded piezoelectric actuators excited under the shear effect. Two types of actuator geometries viz. beam and annular plate are considered, where the material properties are assumed to have a continuous variation in accordance with a power law distribution. The generalized differential quadrature method is used to obtain the solutions, and is compared to exact analytical results. The methodology reported and the numerical results presented will be useful for the design of devices utilizing functionally graded piezoelectric actuators under the influence of shear.

Provides a detailed analysis of functionally graded piezoelectric actuators under shear Demonstrates the efficacy of the generalized differential quadrature method to obtain the natural frequencies of actuators Discusses the applications and advantages of functionally graded piezoelectric materials
