摘要
为在水体—结构动力相互作用问题的有限元分析中实现节点附加质量的批量自动施加,利用ABAQUS软件提供的用户单元子程序接口UEL,开发了四节点三维附加质量单元(M3D4)。算例分析结果表明,M3D4单元可为基于附加质量法的三维水体—结构动力相互作用有限元分析提供简便的处理方法。
In order to realize the batch auto-application of added mass for nodes in FEM analysis of dynamic interaction between water and structure,the four Nodes 3-D added mass element(M3D4)is developed in ABAQUS based on the user element interface UEL.The results show that the M3D4 element gives a simple method to the FEM analysis of dynamic interaction between water and structure,which takes use of the added mass method.
