摘　　要：本文针对舰船Y型复合材料-钢板连接接头做了相关研究,利用有限元方法对复合材料Y型连接接头进行计算,纤维破坏选用三维Hashin失效准则进行校核,夹芯层选用最大应力准则进行校核,并编写UMAT失效子程序进行材料破坏分析,对加筋接头和无筋接头进行计算,最后通过实验方法进行验证。结果表明:加筋能够显著提高Y型预埋钢板接头载荷,并且改变了接头的破坏形式,由接头蒙皮损伤破坏转变成预埋钢板处胶层分层破坏和PVC剪切破坏;另外,随着钢板与PVC距离的增大,接头承载能力降低,破坏也会提前发生。In this paper,the Y-type composite-steel plate joint of warship was studied.The finite element method was used to calculate the Y-type composite joint.The three-dimensional Hashin failure criterion was used for fiber failure,the maximum stress criterion was used for sandwich layer.And the UMAT failure subroutine is compiled to analyze material failure.The reinforced joint and the unreinforced joint were analyzed,and finally verified by experimental method.The results show that the reinforcement can significantly increase the load of Y-type embedded steel plate joints,and change the failure mode of joints from skin damage to delamination damage of adhesive layer and PVC shear failure at the embedded steel plate.With the increase of the distance between steel plate and PVC,the mechanical properties of joints decreases.When the force decreases,the damage will occur ahead of time.
