| 摘 要： | 导出了压电介质弹性稳定性问题的控制微分方程，提出了压电层合板柱形屈曲的数学弹性力学解法．由于最后所得特征值问题的复杂性，屈曲临界载荷必须数值求解．文中对不同压电材料的双层极作了具体计算，考查了压电性对屈曲载荷的影响． |
| 关 键 词： | 压电层合板 柱形屈曲 临界载荷 |

| Abstract: | The governing differential equations of elastic stability problems in piezoelectric ma-terials are deduced. The solution of the cylindrical buckling problems of piezoelectric laminatedprates is presented in the context of the mathematical elastic theory- Due to the complexity of eigen-value problem resulted in, the critical load of buckling must be solved numerically. Numerical re-sults for plates with two layers composed of different materials are presented, the influence of piezo-electricity upon buckling loads are analyzed. |
| Keywords: | piezoelectric laminated plates cylindrical buckling critical load |
