摘要: 本文提出的八结点六面体Q (MM6)单元是在修正了Taylor等人提出的二维非协调元Q (M6)[1]通过分片试验修正条件后,将其推广到三维等参元中得到的。该单元比Taylor等提出的Q (M6)[1]单元计算量小且精度高。算例表明,Q (MM6)单元对多种结构形式和载荷工况都有较好的适应性,在工程计算中有广泛的适用范围,特别是在梁板组合结构分析中具有特殊的意义。

Abstract: The eight-node three-dimensional isoparametric nonconforming element QMMB presented in this paper, based on improving two-dimensional isoparametric non-conforming element passed path test modification condition by professor Taylor et al., using and stretching it for three-dimensional isoparametric element, was then derived. This element QMM6 has an advantage over QM6 presented by Taylor et al. in the time for computation and precision. The example showed that the element QMM6 has the better feature of element, as the increase of the irregular degrees of the element. Then, the element QMM6 can be used in many cases of engineering calculations, especially, for analysis of the structure of combined beam with plate.
