| 英文摘要 | In the use of finite element methods to the planar elasticity problems, one difficulty is to overcome locking when elasticity constant lambda -> infinity. In the case of traction boundary condition, another difficulty is to make the discrete Korn's second inequality valid. In this paper, a triangular element is presented. We prove that this element is locking-free, the discrete Korn's second inequality holds and the convergence order is two. |
