The buckling analysis of a nonhomogeneous cylindrical shell under torsion is studied in the present paper. The shell has nonhomogeneity properties which are assumed as a suitable function through the thickness direction. The stability equations are derived by the adjacent equilibrium criterion method based on the first order shear deformation theory. These equations are employed to analyze the buckling behavior and obtaining the critical torsional loads. A detailed numerical study is carried out to bring out the effects of nonhomogeneity parameter, transverse shear, and aspect ratio on the critical torsional loads. Validity of the present analysis was checked by comparing the results with those are available in the literature.<\div>

The paper presents a stability characteristics prediction for Functionally Graded Toroidal shells (FGTS) with circular cross–section under uniform external pressure. The material properties vary continuously in thickness direction. Sanders–Budiansky shell stability theory specialized for circular toroidal coordinate is used for stability analysis. Also, a two–dimensional differential quadrature method (DQM) is utilized in order to solvestability equations. The numerical results for critical buckling pressure in different geometry and material properties are presented and these results are compared with previous analytical and finite elements studies which indicate that geometry characteristics and changing in volume fraction for FGM have obvious effects on toroidal shells buckling capability<\div>
