摘要
本文对薄板稳定性有限元分析中的精化几何刚度矩阵作了进一步改进，使其列式更为简单，且保持精度高。
A new refined method of the geometric stiffness matrix in the analysis of finite element for stability of the thin plate has been developed. The numerical examples are given to demonstrate that the present method possesses higher accuracy of the critical load, higher calculation efficiency and higher ability to solve the critical load of uniform shear.
