Dynamic analysis of 2–2 cement based piezoelectric composite actuator with considering ambient temperatures

Exact dynamic analysis of 2-2 cement-based piezoelectric actuator is presented based on the theory of piezo-elasticity in this article with considering ambient temperature. The temperature field considered is assumed to be of uniform distribution over the plate surface. The solution of the piezoelectric composite under sinusoidal electric signal was obtained by using displacement method. The effects of amplitude and frequency of the electric signal, ambient temperature and some material coefficients of piezoelectric material are simulated and discussed. The solutions are compare with the numerical results, and good agreements are found. The results obtained in this present investigation provide a theoretical method for applying the cement based piezoelectric composite in civil engineering.
