英文摘要	In this paper, we propose a first-order rectangular nonconforming element for the stress-displacement system derived from the Hellinger-Reissner variational principle for the three-dimensional elasticity problem. We show that the discrete inf-sup condition holds for this scheme. Based on some superconvergence of the consistency error, we prove the optimal error estimate of O(h) for both the displacement and stress.; Mathematics, Applied; SCI(E); EI; 0; ARTICLE; 1; 51-65; 19
