| 摘 要： | 基于具有2个热松弛时间的Green和Lindsay(G-L)广义热弹性理论,研究了无限大旋转厚压电板在上下表面受到条带状热冲击时的广义压电热弹性问题.为避免采用积分变换法求解带来精度降低问题,采用有限元法在时间域内对控制方程直接进行求解,得到了压电板在热冲击作用下的无量纲温度、无量纲位移、无量纲应力及无量纲电势等的变化...

| Abstract: | 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 constitutive equations in time domain directly.The distributions of the dimensionless temperature,stress,displacement and electric potential w... |
