根据连续介质力学和非线性有限元理论，推导了进行板壳结构非线性分析的退化壳元的完全拉格朗日（简称T.L.）法列式，建立了材料在大变形、大应变情况的本构关系。数值算例证明了本文方法的正确性和有效性。 Based on the theory of continuum mechanics and nonlinear finite element method, the complete Lagrangian (TL) method of degenerate shell element for non-linear analysis of plate and shell structure was deduced, and the material of this material under large deformation and large strain Structure relations. Numerical examples demonstrate the correctness and validity of the proposed method.
