Active yielding control for coupled electro-mechanical bending response of piezoelectric functionally graded cylindrical panel based on full layer-wise theory

摘要

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 threedimensional 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.
