| 摘 要： | 建立了大开口船舶舱口角隅应力集中有限元计算模型，讨论了４种应力释放孔孔形以及无应力释放孔时舱口角隅处的应力分布情况，并讨论了加加厚板后的应力分布情况。从实用角度分析了应力释放孔和加加厚板的效果，为解决大开口船舶舱口角隅处应力集中问题提供了计算依据。

| Abstract: | A 3 D FEM model is set up for calculating the stress concentration at hatch corner for a ship with lenge openings.The stress destribution at hatch corner with four kinds of stress releasing holes and without stress releasing hole,as well as with strengthened plates are discussed.The effectiveress of stress releasing hole and strengthened plate is analyzed for reducing the stress cuncentration at the hatch corner for the ship with large openings. |
