AB - <p style="text-align: justify;">In this article, the effects of temperature and size-dependent on the buckling
behavior of functionally graded (FG) cylindrical nanopanels resting on elastic foundation using nonlocal strain gradient theory are investigated in detail analytical approach. According to a simple power-law distribution, the material properties of FG
cylindrical nanopanels are assumed to vary continuously through the thickness direction. The Pasternak model is used to describe the reaction of the elastic foundation on
the FG cylindrical nanopanels. The fundamental relations and stability equations are
derived by applying the nonlocal strain gradient theory and the classical shell theory
based on the adjacent equilibrium criterion. Using Galerkin’s method, the mechanical
buckling behavior of FG cylindrical nanopanels resting on an elastic foundation in the
thermal environment is solved. The reliability of the obtained results has been verified by comparison with the previous results in the literature. Based on the obtained
results, the influences of the material length scale parameter, the nonlocal parameter,
temperature increment, geometric parameters, material properties, and elastic foundation on buckling behaviors of FG cylindrical nanopanels resting on an elastic foundation in the thermal environment are analyzed and discussed.</p>
