摘要
建立了在拉、压、弯、扭组合变形下复合材料薄壁杆件理论,给出了典型薄壁箱梁的等效弹性系数.
In this paper,we established the general theory of composite box beam under the combinational deformation of tension,compression,bending and torsion,discussed the equivalent constitutive equations,and gave the equivalent elastic coefficients about two kinds of typical thin walled beams.
