FORMULAIION FOR GENERALIZED CONFORMING PLATE ELEMENT WITH FERGUSON’S SURFACE
-
摘要: 根据广义协调原理，首先利用Ｆｅｒｇｕｓｏｎ曲面构造出薄板弯曲单元，将中厚度板视为双向深梁，由Ｔｉｍｏｓｈｅｎｋｏ理论拟合单元边界，利用Ｆｅｒｇｕｓｏｎ曲面的张量积性质，将薄板单元推广到中厚度板。数值结果表明此单元精度高，适应性强，且不出现剪切闭锁现象。

Abstract: This paper presents a thin plate element with Ferguson’s surface according to generalized conforming theory,and advances it to moderate thick plate problem,regarding it as two-dimensional deep beam and getting out the functions of element border by using Timoshenko’s beam theorem. Calculation results show it is of high quality.-
