| Abstract: | Instability of shell is a main destructive form of a submarine submerged to a certain depth.The vibration and flexibility principle is applied to research of the instability of submarine.A relation between the natural frequency of stiffened cylinder and water pressure is obtained.Furthermore,the instability pressure is solved.Finally,the calculated result is compared with experimental result and result obtained with finite element method. |
