Summary: | In this paper, the thermal buckling loads of
elliptical thin plates made of functionally graded material (FGM) with
thicknesses that vary parabolically are examined. The aim is to study the
effect of parabolic thickness variations in the directions of both axes on the
thermal buckling of FGM plates. In the analyses, the boundaries are assumed to
be simply supported and clamped. Rayleigh-Ritz method is applied to solve the
partial differential equations. The Poisson’s ratios of the plates are kept
constant, but their moduli of elasticity and thermal expansion coefficients are
assumed to vary functionally in the thickness direction due to the material
characteristics of FGMs. The study is carried out for several plate aspect
ratios. Thermal buckling results of elliptical FGM plates with parabolically
varying thicknesses are determined and the critical temperatures of those
plates are obtained. |
