摘要: 综述了人们在建立研究复合材料薄壁梁力学特性的非线性梁理论及分析结构剖面特性,确立结构算子参数等方面所做的工作以及这些研究工作的特点。同时,结合作者的工作,介绍了近年来各国学者在复合材料薄壁梁力学特性研究上的进展。Abstract: The composite thin-walled beams are widely used in industry because of their good mechanical properties. In this paper, the research work for the composite thin-walled beams about nonlinear beam theory and analysis of the beam cross-section characteristics are surveyed. Dealing with warping displacement,the composite thin-walled work can be divided into six classes: (1) free warping model;(2) one-order warping theory; (3) high-order warping theory;(4) axial warping distribution model; (5) eigen-warping model; (6) the other models. With respect to the mechanical characteristics of the composite thin-walled beams, the recent progresses including the authors' work which considers the laminate warping effect for composite thin-walled beams are introduced.
