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.
