Summary

This paper reports on an investigation into the buckling behaviour of five geometrically imperfect duplex stainless steel tube models, subjected to external hydrostatic pressure, for the first time. The research was partly experimental and partly theoretical, where in the latter case; both analytical and numerical theoretical analyses were carried out.

The experiments were carried out on five stainless tube models of different lengths, using two mild steel end bungs to seal the models. The experimental results showed that the duplex stainless steel specimens behaved similarly to other isotropic materials tested by other researchers.

The theoretical calculations and analyses were made by MisesNP, a DOS-based computer program, together with the ANSYS finite element structural analysis software.

Combining the results of the present series of models, together with the results of other experimenters, a design chart was produced, which can be used for designing imperfect full-scale vessels.
