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.
