As a reliable analysis of the stress of the flat endplate supported by two eccentric circles (one of them is the flxing circle of the endplate to the shell and the other is to the flue) under the uniform pressure, like in the case of Cornish Boiler without gusset stay, has not been done ; the authors dealt with this problem theoretically using the bipolar co-ordinates, and obtained the satisfactory coincidence with the numerical calculation for the practical dimensions, and moreover comparing the values obtained by the approximate solution and its numerical results using the same data which were previously reported by one of the authors, the error of the approximate one was confirmed to be negligible.
