Thermal buckling analysis of functionally graded rectangular nanoplates based on nonlocal third-order shear deformation theory

In this work, thermal buckling analysis of functionally graded rectangular nanoplates is investigated. In order to consider the size effects, nonlocal elasticity theory and third-order shear deformation theory are used. It is assumed that the material properties of functionally graded nanoplates are varied through the thickness of nanoplates according to the power law distribution. Two types of uniform and nonlinear temperature distributions are considered in this paper. To show the accuracy of present methodology, our results are verified with the results available in the literature. Moreover, the influences of different parameters such as nonlocal parameter and piezoelectric layers are studied.
