Stiffening rings for cylindrical for the combined ringshell

Values for calculation

$ T $ $ \mathrm{°C} $
$ P $ $ \mathrm{MPa} $
$ D_o $ $ \mathrm{mm} $
$ L_s $ $ \mathrm{mm} $
$ t $ $ \mathrm{mm} $
$ A_s $ $ \mathrm{mm^2} $
$ I^´ $ $ \mathrm{mm^4} $
$ A $

Calculation

Factor $ B $

$$B=\cfrac{3}{4}\cdot\left(\cfrac{P\cdot D_o}{t+A_s/L_s}\right)$$

Required moment of inertia of the combined ringshell cross section about its neutral axis parallel to the axis of the shell

$$I^´_s=\left[D_o^2\cdot L_s\cdot\left(t+A_s/L_s\right)\cdot A\right]/10.9$$

$$I^´_s\le I^´$$
