船体甲板和侧壁大开口应力集中及其加强形式

Stress Concentration of Large Opening in the Deck and the Sideboard of Ship and Its Strengthening Measures

抽象出船体甲板和侧壁大开口应力分析的力学计算模型，并应用有限元程序，分析了船体中部甲板和舷侧结构在总纵弯曲条件下的应力分布，计算了船体甲板和侧壁大开口的应力集中系数，提出了多种加强措施，并计算了相应的加强效果。

A calculating model about the stress is abstracted. Using finite element method,this paper analyses the distribution of the stress and evaluates the cofficient over the large opening in the deck and the sideboad of thd mid ship when the ship structure is subjected to the total longitudinal bending.It also presents many strengthen measures and evaluates the effect of these measures.
