ALE有限元方法研究及应用

STUDY OF THE ALE FINITE ELEMENT METHOD AND ITS APPLICATIONS

摘要: 将ALE(Arbitrary Lagrangian-Eulerian)描述引入到有限元方法中，从而使有限元方法在解决大范围自由移动边界问题，特别是液体大幅晃动、流-固耦合、加工成型、接触、大变形等问题时获得极大成功. 本文综述了ALE有限元方法的研究现状以及在不同领域的应用，并对今后的研究及应用做了展望.

Abstract: ALE-FEM (Arbitrary Lagrangian-Eulerian Finite Element Method) cansuccessfully be used in solving problems, such as liquid large-amplitude sloshing,fluid-structure interaction, metal forming, andlarge-deformation analysis. This paper reviews the research progress ofALE finite element method and its further development.
