摘要: 建立复合材料层合梁有限元数学模型。对大挠度问题进行分析的同时,着重研究在两个方向上的弯扭耦合关系。计算结果与实验值及其他理论值相比,具有良好的一致性。

Abstract: The coupled bending-torsional deflection analysis of a laminated beam is a special kind of engineering problem. A set of finite-element mathematical formulas which differs from the one of laminated plates and shells is established in the present paper. Which the geometrical nonlinear problem of the beam is investigated, the emphasis of this research is put on the coupling relations between w bending and torsion, v bending and torsion of the laminated beam.The results obtained in the paper are in good agreement with experimented and other theoretical results.
