摘要
提出一种新型的三维无限元坐标映射函数，其概念明确、形式简洁。算例结果表明，采用本文的映射函数进行无限元计算，精度是可靠的。
The new mapping functions of 3-D 12-node infinite element are presented. The mapping functions are clear-cut in the concept and concise in the form. The problems, which emerge in using the infinite element model of the reference [5], don't appear in using the infinite element with the new mapping functions. The results of the examples show that the computational accuracy with use of the new mapping functions is reliable.
