摘　　要：本文建立了拉伸和弯曲耦合层合梁的位移微分方程。导出了拉弯耦合层合梁正应力和层间剪应力的计算公式 ,分析了规则非对称正交层合梁的应力具有非对称特性。当规则非对称正交层合梁的铺层组数大于 8时 。The differentiating equations of displacements have been developed for laminate beam under the coupling of tension and bend. For laminate beam with tension and bend coupling,the calculating formula of normal stress and layer shear stress were educed The stresses of rule-normal and asymmetrical laminate beam were analyzed. The distribution of stresses is asymmetrical.As the number of laminate series is more than 8, the distribution of asymmetrical stresses tends to symmetrical distribution.
