Abstract

AbstractThe current investigation plans to examine thermal buckling of functionally graded material (FGM) plates with various power index (p) and under various rise of temperature, uniform and non-uniform by utilizing a HOSDT-based solid-shell element. By applying the Higher Order Shear Deformation Theory (HOSDT) in the incompatible strain part, the shear strains guarantee a quadratic appropriation across the thickness of plate. The presented solid-shell element doesn't need a shear correction factors. Furthermore, the finite element formulation is ready to beat the locking issues due the use of the Enhanced Assumed Strain (EAS) and Assumed Natural Strain (ANS) method. The exhibition of the grew full three-dimensional component is outlined through the correlations of our outcomes with those accessible in the literature. Then, the effects of some geometric and material parameters on the critical thermal buckling temperature of shell structures are investigated.KeywordsThree-dimensionalSolid-shellFGMThermal bucklingHOSDT
