摘要
提出一薄板矩形协调单元，通过理论证明该薄板单元具有完备性和Ｃ１阶连续性，从而较好地解决了薄板单元的Ｃ１阶连续性难题，并用该协调板单元对薄板进行了对比分析，其计算结果较非协调单元精确，收敛速度快。
In this paper, a harmonized rectangular thin plate element is presented.Analysis has proved theoretically that the element comes to perfectness and C 1 continuity.The C 1 continuity problem is thus fairly well solved.The result obtained from a comparison analysis by using the harmonized plate element is more precise than using unharmonized plate element and the calculation process converges faster too.
