| Abstract: | In FEM practices, the 9-parameter element for thin plates is used widely in engineering practices, as it is simple in shape and convenient to use. in this paper, on the foregoing basis, a geometric stiffness matrix based on adjusting parameter is proposed and the consistent stiffness matrix of 9-parameter element for thin plates is revised. It offers a method to promote the accuracy for the analysis of stability of thin plates and the related formulas are not complicated. Numerical results show that this is reliable. |
