摘要
本文在作者们以前工作的基础上导出了热压电介质弹性稳定性问题的控制微分方程，提出了热压电层合板热屈曲问题的数学弹性力学解法．由于最后所得特征值问题的复杂性，热屈曲临界温度必须数值求解．文中对不同压电材料／非压电材料层构成的层合板作了具体计算，考虑了压电性对屈曲温度的影响．
In this paper, the governing differential equations of elastic stability problems in thermopiezoelectric materials is deduced. The solution of the thermal buckling problems of piezoelectric laminated plates is presented in the context of the mathematical theory of elasticity. Due to the complexity of eigenvalue problem resulted in, the critical temperature values of thermal buckling must be solved numerically. Numerical results for piezoelectric/nonpiezoelectric laminated plates are presented, the influence of piezoelectricity upon thermal buckling temperature are discussed.
