摘 要: 本文研究了内参型非协调元附加内部自由度的有效数目,结合平面四结点元讨论了有效附加内部非协调位移的合理形式。 Rational displacement fields in incompatible elements are discussed in this paper. The new concept of the effective number of additional internal degrees of freedom in incompatible elements is proposed. A new method to select the rational displacement fields of the 4-node plane incompatible element is developed.
