Abstract :
In this article, shear buckling analysis of functionally graded porous annular sector plate reinforced with graphene nanoplatelets (GPLs) are investigated for the first time. The plate is consisting of a layered model with uniform or non-uniform dispersion of graphene platelets in a metallic matrix including open-cell interior pores. The extended rule of mixture and the modified Halpin-Tsai models and are employed to obtain the effective mechanical properties of the porous nanocomposite plate. Three different porosity distributions in conjunction with five patterns for dispersion of GPL nanofiller are considered through the thickness of plate. Governing equations derived according to the principle of minimum total potential energy based on 3D elasticity theory and generalized geometric stiffness concept. Finally, finite element method is applied for solving the governing equations of structure. The influence of different parameters including various porosity distribution, porosity coefficient, patterns of GPL dispersion, weight fraction of GPL nanofiller, boundary conditions and sector angles on shear buckling loads of the annular sector plate has been surveyed.
