摘 要:
用无单元法研究了薄板的几何非线性问题，从移动最小二乘法和变分原理出发，推导出了无单元法的几何刚度矩阵，编制了相应的程序，并给出了算例．结果表明，方法合理可行，同有限元相比处理过程更加简单．[著者文摘]

Abstract:
In this paper, the element-free method （EFM） is used to study the large deflection analysis of thin plates. The corresponding geometric stiffness matrix is derived, using the moving least-square method and variatior principle. Numerical Results show that the method possesses a higher accuracy as compared with the finite element method for the large deflection analysis of thin plate.[著者文摘]
Key words:
