o:30038 Comparative Thermal Buckling Analysis of Functionally Graded Plate en Abstract: A thermal buckling analysis of functionally graded thick rectangular plates accord¬ing to von Karman non-linear theory is presented. The material properties of the functionally graded plate, except for the Poisson’s ratio, were assumed to be graded in the thickness direction, according to a power-law distribution, in terms of the volume fractions of the metal and ceramic constituents. Formulations of equilibrium and stability equations are derived using the high order shear deformation theory based on different types of shape functions. Analytical method for determination of the critical buckling temperature for uniform increase of temperature, linear and non-linear change of temperature across thickness of a plate is developed. Numeri¬cal results were obtained in МATLAB software using combinations of symbolic and numeric values. The paper presents comparative results of critical buckling tempera¬ture for different types of shape functions. The accuracy of the formulation presented is verified by comparing to results available from the literature. Keywords: thermal buckling, von Karman non-linear theory, shape function, higher-order shear deformation theory, power-law distribution 1552099 10.2298/TSCI160614182C 1552101 0354-9836 2023-06-05T15:01:20.363Z 44 no 46 Dragan Čukanović Ljiljana Veljović person Igor Balać person Gordana Bogdanović person Aleksandar Radaković Državni univerziet u Novom Pazaru person 62932233 0000-0002-7355-7403 Dragan Milosavljević person 0000-0001-9144-5416 application/pdf 9304913 https://phaidrabg.bg.ac.rs/o:30038 no yes 18 70 92000001 20A01 Thermal Science 2017 21 6 2957 2969 2017
