This offers the Ist summary of the report of the experiments to investigate the stress concentration and stress distribution of thin-walled cylinders with various sorts of holes, such as circular, triangular, rectangular, square, ellipse, compound and etc. The theoretical analyses and experiments on the two-dimensional elastic problem of plane with various kinds of holes, above mentioned, subjected to tension were carried out to some extent and we have already many good results obtained. But few results on the problem of thin cyl. with holes under axial loads. The specimens used are large type of thin cyl. with holes of length 320mm, outside dia. 67.3mm, thickness 2mm. The maximum stress concentration occurred on the periphery of the hole, especially in the circumferential direction of the cyl. as we had presumed before the test. The stress concentration of the cyl. with a single hole was fairly big in comparison with that of the cyl. with a penetrated hole as the empirical results indicated.
