Elastomer is the key component of the flex-joint of deep-water riser, which is bonded with major structure.The bonded interface corner of these two components is liable to be damaged.In order to investigate the failure mechanism,finite ele-ment software ABAQUS was used to analysis stress field of rubber-steel bonded interface corner and its influencing factor.The re-sults showed that stress field of rubber-steel bonded interface corner would form stress concentration and the maximum stress is at the path of.The change of interface bounded angle would affect the stress magnitude of rubber-steel bonded interface corner,but this effect is small.%弹性体为深水立管柔性接头关键部件,与主体结构粘结的界面端附近为易发生损伤部位,针对其破坏机理问题,采用有限元软件ABAQUS对橡胶-钢粘结界面端的应力场及其影响因素进行分析,结果表明:橡胶-钢粘结界面端附近应力场存在明显的应力集中现象,并在θ=60°这一路径上的应力最大;改变界面端结合角可以影响橡胶-钢粘结界面端应力大小,但影响很小.
