A NEW TRIANGULAR GENERALIZED CONFORMING ELEMENT FOR THIN THICK PLATES

摘要: 本文提出了一种假设单元剪切应变场的新方法,基于广义协调理论构造了一个只有9个自由度的三角形厚薄板通用单元TCGC-T9.数值算例表明:该单元具有自由度少,精度高,无剪切闭锁现象等特点,适用于从极薄板到厚板较大的范围。

Abstract: In this paper, a new simple method considering the influence of shearing deformation in plate bending problem is proposed. According to this method and several generalized conforming conditions, a new triangular element with only 9-D.O.F. for both thin and thick plates is constructed. Numerical examples show that the element is effective for a large range of thickness span ratio from very thin plate to thick plate.
