| Abstract: | An experimental study for 3 cylindrical shells with a different d/D ratio opening nozzle was done. It's objective is to provide a detailed stress distribution in the vicinity of nozzle-cylindrical shells. Results indicate that the stress distribution of shell and nozzle shows the bilateral symmetry in the longitudinal plane. The scope of stress concentration is limited. Under the same load, the maximum stress decreased and the ratio of stress didn't vary during the ratio of d/D increasing. |
| Keywords: | cylindrical shell opening experimental study limit load stress analysis |
