| Abstract: | Taking the double bottom structure of the ship as the study object to do model test, the hole-edge stress distribution of the holes on the panels under pressure load is studied. The paper analyzes the influence of different reinforcement forms and different hole types under pressure load on the hole-edge stress distribution. On the basis, the related simulation analysis is carried out. The comparison between the test results and the numerical simulation results verifies the accuracy of finite element simulation. |

| Keywords: | pressure load through holes for longitudinal hole-edge stress hull structure model test numerical simulation |
