一个简单、有效的四节点板弯曲单元

A SPIMLE AND EFFEC TIVE FOUR NODES PLATE BENDING ELEMENT

摘要: 本文依据拟协凋元列式方法,构造了一个四节点的Mindlin类型板弯曲单元,该单元具有节点自由度少,形状任意,对板的厚跨比有相当宽的适用范围。数值结果表明,该单元具有通用性强,精度好,既使在单元形状严重畸变时,该单元仍具有较好的数值性能。

Abstract: Based on Quasic-Conforming Technigue, a simple and effective four nodes for thin and moderately thick plate bending (coresponding to Mindlin Plate theory) has been developed.
