Thermal buckling analysis of polymeric piezoelectric nano-plate resting on elastic foundation

In this research, thermal buckling of rectangular plate made of plyometric piezoelectric (Polyvinylidene fluoride) is analyzed for the first time. First order shear deformation plate theory, piezoelectricity theory and Eringen’s nonlocal elasticity theory are utilized to derive the five equations of motion. Pasternak foundation is selected to modelling of elastic medium due to considering both normal and shears modulus. Electric field are uniformly applied on polymeric piezoelectric nano-plate in x directions. Nonlocal motion equations are derived using Hamilton’s principle and solved by differential quadrature method (DQM). Results indicate the effect of various parameters such as aspect ratio, thickness ratio, elastic medium, electric potential, shear correction factor and small scale effect on the critical thermal buckling load of nano-plate. These finding can be used to of micro and nano smart structures in many industries.
