If the allowance thickness be somewhat constant, independent of the size of the ship, the induced stress, which depends on the thickness of the shell platings, will approach towards some asymptotic value, when the ship's size be made indefinitely large, as the allowance thickness becomes infinitisimally small compared with the thickness, necessary for strength only. The so-obtained value may be considered as the allowable stresses purely necessary for the strength of the ship. Then, using this value, the thickness necessary only for the strength can be calculated for the ship of usual size, and the allowance thickness for corrosion may be determined. Such a method is applied to the bottom shell platings, and reasonable values for allowance thickness are obtained.
