Buckling Analysis of Stiffened Cone-Cylinder Intersection Subjected to External Pressure

Abstract:

This paper aims to examine the influence of ring stiffener reinforcement on the buckling behavior of cone-cylinder intersection subjected to external pressure. Three different stiffener locations were analyzed; they are (i) cone-cylinder intersection, (ii) cone mid-section, and (iii) cylinder mid-section. Internal and external stiffeners are used in the study. Buckling strength of the stiffened cone-cylinder intersections were obtained with the aid of FE analyses for all the cases above. Cone-cylinder intersections are modelled as elastic-perfectly plastic of Hiduminium alloy (HE-15). Validations of the present results with the published experimental data were presented. Result indicates that the introduction of stiffener reinforcement in externally pressurized cone-cylinder intersections seemed to be desirable in a preliminary design process, thus promotes a stronger shell to resist buckling.
