Buckling Investigation of Ring-Stiffened Cylindrical Shells Under Unsymmetrical Axial Loads.

摘要

Two buckling experiments are described in detail. The first purpose of these experiments is to establish baseline values for the buckling loads and modes for ring-stiffened cylindrical shells that have geometric parameters characteristic of the ring-stiffened cylindrical section of a typical nuclear steel containment vessel. A series of follow-on experiments on nominally identical ring-stiffened cylinders that have framed and reinforced penetrations typical of nuclear industry practice are planned and will be described in a separate report. This report is issued separately because of the volume of detail included on methods, measurements, and data reduction techniques. In addition, a second purpose of these experiments is to serve as a set of benchmark experiments for computer codes that can predict buckling loads for axisymmetric geometries, and in this respect this work stands alone. Complete material stress-strain curves are described and complete geometric imperfection data for the shells are given.
