Static Analysis of Simply Supported Functionally Graded Piezoelectric Beams Under Thermal Loads

In this article, static analysis of functionally graded piezoelectric beams based on the first-order shear deformation theory under thermal loads is investigated. The beam with functionally graded piezoelectric material (FGPM) is graded in the thickness direction and a power law distributes the piezoelectric material properties. The electric potential is assumed linear across the beam thickness. The governing equations are obtained using the potential energy and the Hamilton’s principle. The exact solution of simply supported functionally graded piezoelectric beam is obtained by the finite Fourier transformation. Results are presented for different power law indices under thermal gradient.
