In this article, a highly efficient quasi-three-dimensional theory has been used to study the nonlinear hygro-thermo-mechanical bending analysis of a very thick functionally graded material (FGM) rotating disk in hygro-thermal environment considering the porosity as a structural defect. Two applied quasi-three-dimensional displacement fields are assumed in which the strain along the thickness (ez) is not zero unlike most of the other plate theories. By considering the nonlinear strains (von Karman’s assumptions) the large deformations have also been taken into account in order to obtain more accurate results. Finally, some factors that affect the results have been studied further.
