This paper analyzed the penalty function pseudo-nodes displacement consistent method. Based on these methods, non-pseudo-nodes displacement consistent method is presented, which solved the problem of the displacement consistency between meshes with different densities. The formulations of the methods are deduced. Consequently the contradiction between calculation accuracy and efficiency is coordinated. Non-pseudo-nodes displacement consistent method provides symmetric banded matrices. The validity of the proposed method is verified by an example. The results show that the accuracy and efficiency of the method are satisfactory.
