FORMULATION OF A GENERALIZED CONFORMING ELEMENT FOR MODERATE THICK PLATE BASED ON COONS' SURFACE

    摘要
  • 摘要: 本文在1的基础上,利用Timoshenko深梁理论拟合边界挠度,由广义协调原理构造单元内部位移场,得出一种适用于中厚板的广义协调元。算例说明本单元具有良好的精度,且不出现剪切闭锁现象。

     

    Abstract: in this paper,a generalized conforming element of moderate thick plate is formulated based on Coons' surface.Timoshenko's beam theory is used to interpolate the boundary displacements along each side of the element(Numerical examples illustrate that the present element gives results with high precision and is free of shear locking.
