The goal of this study is to fill apparent gap in the area about investigating effect porosity distributions on vibrational behavior FG sectorial plates resting a two-parameter elastic foundation. response medium formulated by Winkler/Pasternak model. internal pores and graphene platelets (GPLs) are distributed matrix either uniformly or non-uniformly according three different patterns. model proposed with material parameters varying thickness plate achieve graded both nanofillers. modulus nanocomposite obtained using Halpin-Tsai micromechanics annular sector assumed be simply supported radial edges while any arbitrary boundary conditions applied other two circular including supported, clamped free. 2-D differential quadrature method as an efficient accurate numerical approach used discretize governing equations implement conditions. convergence demonstrated validate results, comparisons made between present results those reported well-known references for special cases treated before, have confirmed accuracy efficiency approach. It observed that maximum vibration frequency case symmetric GPL distribution, minimum uniform distribution. Results show better understanding mechanical plates, it crucial consider porosities inside structure.
