Abstract
A piezoelectric material can be used as a sensor and actuator in active vibration control of a smart structure. The performance of the piezoelectric material is defined by piezoelectric coefficient and dielectric constant. These parameters vary with change in temperature. In this article, the temperature dependence of piezoelectric coefficient and dielectric constant is included in the constitutive equations of the piezoelectric materials. These modified constitutive equations are included in the finite element model of a smart structure instrumented with piezoelectric patches. Simulations are done in MATLAB® software for both modified and non-modified finite element model and shown in the results.
