Abstract
This paper addresses the thermal buckling of actuated functionally graded piezoelectric porous nanoplates. Eringen's nonlocal elasticity theory with a higher-order shear deformation theory are used to obtain the analytical solution. The FGP porous nanoscale plate material possesses smooth continuous gradient transition of properties between materials as the dimension varies according to a modified power law function. The plate is under the influence of several thermal loadings (uniform, linear, nonlinear thermal difference) and electric voltages. A closed form solution of simply-supported FGP porous nanoplates is obtained using Navier's method. The critical thermal buckling of FGP porous nanoplates subjected to several thermal loadings and electric voltages is investigated. Numerical examples are presented to validate the present formulation. The influence of several porosity coefficients, small-scale parameters, thermal loadings, geometric parameters, power law exponents and external electrical voltages on the thermal buckling of FGP porous nanoplates are discussed.
