摘要
本文给出了层合板位移增量型的平衡微分方程。定量地估计了横向剪切变形对四边铰支的正交异性板弯扭耦合效应的影响。结果表明：四边铰支的正交异性层合板，当其长厚比小于３０时，横向剪切变形对其位移和应力的影响是不容忽略的。
The differential equilibrium of displacement increase type of laminate was developed.The effects of bend and torsion coupling of laminate by hinged support have been evaluated quantitatively.The results showed that the effects of traverse shear on displacement and strees are not ignorable,as the length thick ratio of laminate is less than 30.
