The object of the present work is to study the effect of coaming plates on the flexural stresses in a deck plating. Although flexural stresses in a plain perforated plate were dealt with some years ago by W. G. Bickley, I. Nakayama and J. N. Goodier, those problems with a flanged circular hole seem to have never been treated. The solution of the problem is easily obtained by using the results of plane stresses described in my previous paper [J. of Zosen Kiokai, Vol. 54 (1934)].
In case of the infinitely strong coaming plate, the solution entirely agreed with that of a plain perforated plate under some corresponding forces. The first part of this paper dea's with mathematical analysis of the problem and the 2nd part numerical calculations for practical examples. As a supplement, the correspondency between a perforated plate under some plane forces and a bent plate clamped at the rim of a hole is treated.
