摘要
本文针对某型舰船甲板大开口在总纵弯曲力矩作用下的应力集中现象，抽象出力学计算模型。应用先进的有限元分析系统（ＳＵＰＳＡＰ），采用二次计算的方法，详细分析了大开口处各种角隅形状的应力分布，获得了相应的应力集中系数。
A finite element model of ship with a large opening on the deck was constructed to study the stress concentration under the load of longitudinal bending moment.The stress distribution of openings with different corner shapes was analyzed in detail and stress concentration factors were obtained for these corner shapes.
