The purpose of this paper is to explore the buckling problems of functionally graded conical shells due to thermal loadings. The response is obtained for a uniform increase in temperature along the thickness direction of the shell. The equations governing the behavior of the conical shell are written from the modified Reissner-Mindlin formulation. Properties of the shell are estimated using the Voigt rule of mixture via the power function. The temperature dependence of the material constituents is also considered. A comparison study of the obtained results with those available in the literature is presented in order to validate the proposed model. Then, the effects of the power-law exponent and geometrical parameters are examined.
