摘要

在本研究中，基于Gâteaux微分导出了两个新的泛函，以分析对称交叠层复合材料直梁的屈曲。该函数包括四个自变量，即Timoshenko梁的挠度、旋转、剪切力和弯矩，以及Euler-Bernoulli梁的挠度和弯矩。通过几个算例，介绍了所提出的混合有限元公式的应用可能性和性能。

An alternative method for analysing buckling of laminated composite beams

In this study, two new functionals are derived based on Gâteaux differential in order to analyse buckling of symmetric cross-ply laminated composite straight beams. The functional comprises four independent variables, i.e. deflection, rotation, shear force and bending moment for Timoshenko beam, and two independent variables, deflection and bending moment, for Euler-Bernoulli beam. The application possibilities and performance of the proposed mixed finite element formulation are presented on several numerical examples.
