This study's objective is to propose a full 3D finite element modeling for examining the geometrically nonlinear (NL) response of functionally graded (FG) porous materials with plates, ring, and cylindrical shapes. An improved first-order shear deformation theory (IFSDT) utilized in order develop solid-shell element. The governing equations are developed way that offers parabolic distribution transverse strains through FG shell thickness zero condition stresses on top bottom surfaces. given IFSDT has ability model any kind structures incorporates material law. In this study, two types porosity functions considered. effectiveness present demonstrated linear (L) NL numerical examples. effect distribution, coefficient, power-law index, geometrical design parameters, boundary conditions shells evaluated.
