摘　　要：综述了面向对象有限元方法的研究现状。基于国内外大量相关文献,首先评述了有限元方法的面向对象分析过程(OOA),包括对象的识别,对象属性、方法和关系的确定等等。其次涉及有限元方法的面向对象设计过程(OOD),具体讨论了人机交互、任务管理和数据管理等内容。再次讨论了有限元方法的面向对象编程过程(OOP),如编程语言的选择、面向对象有限元的应用和集成等问题。此外还延拓到面向对象方法增强有限元软件的表现、面向对象有限元的扩展等。最后展望该方法的发展动态。In this paper, the current researches on object-oriented finite element were summarized. Based on many relative papers, at first the object-oriented analysis of finite element method (FEM) was reviewed, including identifying objects, confirming attributes, methods and relationships of objects. Second, the object-oriented design of FEM which deals with user interface, tasks management and data management was discussed. Third, the object-oriented programming of FEM was talked over, concerning the choice of program languages, the application and integration of object-oriented FEM. Also, the review includes the comments on the enhancement performance of object-oriented method in finite element software and new technical trends in object-oriented FEM. At the end of this review, a prospect for further development was presented.
