WebSTRESS IN COMPOUND THICK CYLINDRICAL SHELLS In order to withstand a high pressure, the thin cylindrical shell is wound with a wire under tension. The effect of the wire is to put the cylinder wall under a initial compressive stress. The same principal is used in thick cylindrical shells. This is done by shrinking one thick shell over another.
