| Abstract: | This paper introduces an FEM simple 3-D model for the analysis of container ship hatch corner stress concentration.The factors which affect it are discussed.Several hatch corner models are designed to reduce the concentration stress. From practical points,a model has been chosen. Based on this model, an empirical formula of the stress concentration factor is formed according to the theory of similarity. This formula is applicable to the prediction of the hatch corner stress concentration factor of the similar ships. |
