The buckling strength of a thin pipe under external pressure had been theoretically analyzed by von Mises. However, the strength of a thin pipe with locally thinned parts had not been studied. In the previous paper, the present authors showed that the buckling strength for such a pipe decreases in a great deal compared with that of a pipe having no thinned part. Also, it was suggested that the specimen having two thinned parts may show lower strength than the specimen with a single thinned part. This paper reports the experiments carried out in order to ascertain the above suggestion by using the specimens having no pipe end restriction to deformation. The experimental results did not show any dependence of strength on the number of thinned parts, and this was explained by the stress distribution in the pipe.
