Abstract

The critical external pressure at which a thin cylindrical liner may buckle elastically has gained many researchers' attention. In contrast, the inelastic buckling pressure of thick cylindrical liners has never been examined thoroughly. A previous attempt was reported by Jacobsen who had limited the critical external pressure to the value that coincided with the onset of yielding of the most heavily stressed part of the cylindrical liner. The liner thickness-to-diameter and yield stress-to-Young's modulus ratios, both control the ultimate capacity of any liner. This paper presents a parametric study using the Finite Element Method (FEM), evaluates Jacobsen solution and provides charts that help in estimating the ultimate pressure capacity of such cylindrical liners.
