一种基于纵横向有限条带的矩形薄板弯曲单元

A RECTANGULAR PLATE BENDING ELEMEMNT BASED UPON FINITE STRIP IN LENGTH AND BREADTH

摘要: 本文基子单位宽纵横向有限条带的变位模式,构造了一个12个自由度的矩形薄板弯曲单元,此单元满足了单元边界C¹连续性,且自由度少,计算精度较高,可用于大型板系结构的计算分析。

Abstract: In this paper, a rectangular plate bending element with 12 degrees of freedom is presented based upon unit width finite strip in length and breadth. The C¹ continuity condition is sandied at the element boundary. The element is characterized by less degrees of freedom and high accuracy. It is suitable for the computation of lop plate structures.
