Abstract
In this study, examination of buckling behavior of functionally graded piezoelectric (FGP) plates with porosities is conducted employing a refined four-variable plate theory. By capturing shear deformation effects, the present inverse trigonometric theory is needless of shear correction factor. Electro-elastic material properties of porous FGP plate vary across the thickness based on modified power-law model. Implementing an analytical approach which satisfies different boundary conditions, governing equations derived from Hamilton's principle are solved. The obtained results are compared with those provided in literature. It is indicated that the buckling behavior of piezoelectric plates is significantly influenced by elastic foundation parameters, external voltage, porosity distribution, power-law index, boundary conditions and aspect ratio
