封闭式横截面薄壁组合梁的弯曲—扭转性能

对单室箱形结构中的薄壁复合梁的静力和动力特性进行分析。结构模型中考虑了多种非典型作用，如：材料各向异性、横向剪切、翘曲的抑制作用、非均匀扭转模型和转动惯量。利用扩展的Hamilton原则推导出主导方程，并利用扩展的Galerkin方法进行解释。考虑了纤维方向对静挠度和自然频率的影响，得出一些重要结论。

Flexural-Torsional Behavior of Thin-Walled Composite Beams with Closed Cross-Section

This paper investigates the static and dynamic characteristics of composite thin-walled beams that are constructed from a single-cell box. The structural model considered herein incorporates a number of nonclassical effects, such as material anisotropy, transverse shear, warping inhibition, nonuniform torsional model and rotary inertia. The governing equations were derived using extended Hamilton's principle and solved using extended Galerkin's method. The effects of fiber orientation on static deflection a...
