Abstract. In this study, a static response of FGM shells containing even distribution of porosity is investigated using a trigonometric shear deformation theory accounts for effects of transverse shear and normal strains. The principal of virtual work is used for obtaining governing equations and boundary conditions of the current theory. The theory satisfies zero transverse shear stress conditions at the top and the bottom surfaces of the shell. The simply-supported FGM shell is analyzed in the present study using the Navier method. The present results of displacements and stresses in FGM shells are obtained and compared with other higher order theories available in the literature to verify the current theory.
