摘要
介绍了双重渐近近似法(DAA)在商用有限元软件上的实现方法,对包括从基本理论到数值方法、编程实现及稳定性等一系列问题进行了探讨,并将一阶DAA方法在ABAQUS上实现。最后以弹性方板受水下爆炸时的响应作为算例,同纯有限元法进行了比较,表明所用方法是切实可行的。
The way to implement DAA method in commercial FE software is introduced. A series of problems are discussed including basic theory, numerical method, programming, accuracy and stability. DAA method is embedded into ABAQUS and an elastic plate is analyzed as a numerical example. It is proved that the presented method is feasible and some suggestions are given。
