摘要/Abstract

摘要： 本文提出的平面四结点非协调等参元Q (MM6)是用”求逆犯规”方法修正了Taylor和Wilson提出的平面Q (M6)单元满足“分片检验”修正条件[1]后得到的。该单元与Q (M6)单元[1]相比具有计算量小，反映单元畸变特征好等优点。将其推广到三维问题与文献[7]给出的块体Q (M6)单元相比上述优点更为明是。

Abstract: The plane four-node isoparametric non-conforming element presented in this paper is based on improving plane element QM6 by professor R. L. Taylor and E. L. Wilson, using the method of irregular inversion and considering the consideration of patch test. Compared with QMB, the element has the advantage of small computation and highprecision for element irregular, and the advantage is more obvious when stretched to three dimensional problem anal compared. With, the eight-node three-dimensional element QM6 in Ref.
