| 摘 要： | 基于Vlasov理论,本文建立了任意形状闭室复合材料薄壁梁限制扭转力学分析的分层翘曲模型.文中考虑了剪切和翘曲的影响,并分析了材料和铺层对翘曲位移与应力的影响,建立了相应的升阶谱元法,算例表明,复合材料薄壁梁各分层的翘曲位移及应力相差较大.

| Abstract: | Based on Vlasov theory, a layered warping model was presented for mechanical analysis of composite thin walled beams with arbitrary closed section. Besides the effects of shearing strain and torsion warping, the influences of materialsand the ply arrangement on the warping displacement and stress are also discussed. The numerical results show that the warping displacement and stress of the composite thin walled beam are differ from layer to layer due to influence of materials and the ply arrangement. |
