摘要
给出一个三维十二节点无限元的新模型，其映射函数概念明确、形式简洁。该模型不存在文献［７］中无限元模型在计算时出现的问题。另外，结合算例将该模型与文献［８］中无限元模型进行了比较。结果表明，本文的无限元新模型在性能和精度方面均具有优越性。
A novel model of 3D 12_node infinite element is presented in this paper.The mapping functions in the novel model are clear_cut in the concept and concise in the form.The problems,which emerge in using the infinite element model of the reference, appear in using the novel model.A comparison between the novel model and the infinite element model of the reference is made by computing the examples.The results show that the novel model has the advantages in performance and accuracy.
