Static Bending of Isotropic Circular Cylindrical Shells Based on the Higher Order Shear Deformation Theory of Reddy and Liu

Abstract In this paper, a displacement based shear deformation theory formulated on the cubic in-plane field equation of Reddy and Liu is presented for static bending analysis isotropic circular cylindrical shells. The adopted accounts quadratic (parabolic) distribution transverse through shell thickness as well satisfies need stress free upper lower boundary surfaces shell. equations equilibrium are obtained application principle virtual work. Numerical results displacements stresses simply supported A comparison made to those Kirchhoff-Love varying length mean – radius curvature ratios, shows good agreement thin shells irrespective ratio ( l / ). sharing effect found be noticeable in thick shells, however, diminishes with continuous increase ratios.
