| 中文摘要: |
| 推导了平面四点及五点理性元公式，具有完全二次解的插值近似，完全通过分片试验，不发生零能模式，不发生剪切自锁。数例表明本文理性元的优越性。 |
| 英文摘要: |
| The formulations of plane rational finite elements with 4 and 5 nodes, which have complete quadratic solutions of plane elasticity, are derived. They pass the patch test and have high accuracy. Zero energy model, shear locking and volume locking do not exist. Numerical examples show the advantages of the elements. |
