On thermal snap-buckling of FG curved nanobeams

In the present work, we perform the thermal snap-buckling analysis of functionally graded (FG) curved nanobeams. The curved FG nanobeam is subjected to uniform temperature distributions across the thickness. The material properties of the nanobeams are temperature-dependent. Nonlocal strain gradient theory is employed to capture the size effects. Nonlinear governing equations of the FG curved nanobeams with clamped ends are derived via Hamilton's principle and Akavci's beam theory. In the end, the effects of thermal loadings, nonlocal parameter, strain gradient parameter, power law index on the snap-buckling of the nanobeams are discussed.
