For investigation of the stress concentration around the notch or crack of a plate, by using the hypotrochoidal co-ordinate [numerical formula] namely, by using a triangular-shaped hole with sharp or roundish corner, how much stresses decrease due to the roundness of corner was discussed. The author investigated the following items. (1) The effect of stress around a hole due to the change of roundness of corner, under uniform tension, simple shear and simple bending. (2) The stress distribution of plate at neighbourhood of sharp corner under uniform tension at right angle to the corner. (3) Above case, infeering the effect of stress distribution of plate on the line of corner owing to its roundness, some hints for strengthening the plate having sharp-corner was gaind.
