Abstract:

The nonlinear axisymmetric deformation of pressurized cylindrical shells is analyzed and the Tresca Yield Condi tion used to establish a relationship between the limit load, defined as the axial load corresponding to the initiation of plastic action, and the internal pressure. An experimental investigation of the inelastic buckling of pressurized cylinders is also carried out. Both reinforced and unreinforced cylinders are considered the reinforcement consisted of integral ring stiffeners. The limit load is determined for each of the unreinforced models. Agreement between the theoretical and experimental results critical stress level and mode of failure is favorable, indicating that the theory satisfactorily predicts the behavior of axially compressed cylindrical shells for relatively high values of the internal pressure parameter. Finally, the variation of the limiting axial load with internal pressure is evaluated for three cylinders. Comparison with the corresponding elastic buckling curves reveals that, at high values of the internal pressure parameter, plastic buckling will occur at an axial load considerably less than the elastic buckling load.
