The Effect of Rotation on the Dynamic Response of a Generalized Piezoelectric-thermoelastic Problem
The dynamic response of a thick piezoelectric plate subject to strip-like thermal shock on both surfaces is investigated. The piezoelectric plate rotates around a fixed axis with constant angular velocity, and the generalized thermoelasticity with thermal relaxation is applied to formulating such problem. The governing equations considering the rotation effect are derived and numerically solved by means of finite element method. The distributions of dimensionless temperature, stress, displacement and electric potential are illustrated. The results show that the direct finite element method provides an effective way for achieving high calculation precision in solving the generalized piezoelectricthermoelastic 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.
