Based on the generalized thermoelastic theory postulated by Green and Lindsay(G-L), the dynamic response of an infinite rotating piezoelectric plate subject to thermal shocks on both up and bottom surfaces was investigated. To avoid the calculation precision loss caused by the integral transform technique, the so-called direct finite element method was used to solve the governing equations in time domain directly. The distributions of the dimensionless temperature, stress, displacement and electric potential were presented graphically. The results show that the direct finite element method provides an effective way for achieving high calculation precision in solving the generalized piezoelectric-thermoelastic problem. The results also show that the rotation effect tends to decrease the dimensionless displacement and electric potential and barely affects the dimensionless temperature and stress.
