| Abstract: | Using the two-moment limit interaction yield condition, five kinds of collapse mechanisms for various geometric parameters of spherical shells with compact reinforcing nozzles are concerned. The completed solutions and the conditions of validity for each mechanism are determined. The results obtained by the presented paper, which are in good agreement with four experimental results, can be used in pressure vessel design. |
