EVALUATION OF THE COLLAPSE PRESSURES OF A RING-STIFFENED CYLINDRICAL SHELL UNDER EXTERNAL HYDROSTATIC PRESSURE USING CODE FORMULATIONS AND FEA

摘要

In this paper the collapse of a ring-stiffened cylindrical shell under external hydrostatic pressure is evaluated using code formulations (ASME (1992), BSI (1990), and GL (1988)) and nonlinear elastic-plastic finite element analysis. Some conclusions and comments are addressed from the comparison between the results obtained from the used approaches.
