On the Tension of an Infinite Strip Containing a Square Hole with Rounded Corners
Makoto ISIDA · Bulletin of JSME · 1960
The tension problem of an infinite strip containing a square hole with rounded corners is treated by the method of perturbation, convenient formulas for the stress are given and numerical results are examined. The concept of "equivalent elliptic hole" given by F. Hirano in problems of perforated infinite plates is found to be not so valid for the present strip problem. On the other hand, the approximate method proposed by the author for the case of an elliptic hole is still applicable to this problem. In this connection, the author gives an advice on applying this method to other problems of multiply-connected domains.
