In the present study, for investigating the elasto-up to yielding behavior of a piezoelectric functionally graded cylindrical panel with simply supported boundary conditions subjected to electro-mechanical loads, a three-dimensional full layer-wise theory is employed. The material properties of the panel based on a power-law function change continuously through the thickness of the panel. The trigonometric terms are employed to present an analytical solution for the stress field distribution. For investigating the yield modes of the functionally graded cylindrical panel, the von Mises yield criterion is compared with TTO (Tamura– Tomato– Ozawa) model which has been not reported hitherto. The commercial ABAQUS is employed for verification of the results which are obtained by using full layer-wise theory. The results of stress and displacement fields are presented graphically and the effect of adding piezoelectric sensor-actuator to the functionally graded cylindrical panel and applied voltage on the yield modes of the panel are investigated. Yield modes of the panel vary through the thickness of the panel. After adding the piezoelectric sensor-actuator to the FGM cylindrical panel, and changing the applied electrical voltage the yield modes of the panel are controlled.

在本研究中，为研究压电功能梯度圆柱板在承受机电载荷的情况下的弹性屈服行为，采用了三维全层理论。基于幂律函数的面板材料特性会在面板厚度范围内连续变化。三角项用来表示应力场分布的解析解。为了研究功能梯度圆柱板的屈服模式，将冯·米塞斯的屈服准则与迄今尚未报道的TTO（Tamura– Tomato– Ozawa）模型进行了比较。商业ABAQUS用于验证通过使用完全分层理论获得的结果。以图形方式显示了应力场和位移场的结果，并研究了向功能梯度圆柱面板添加压电传感器-执行器以及施加电压对面板屈服模式的影响。面板的屈服模式随面板的厚度而变化。在将压电传感器-执行器添加到FGM圆柱形面板后，更改施加的电压，即可控制面板的屈服模式。
