摘要
在考虑几何非线性的前提下,计入各种耦合效应,利用复合材料层合板理论对薄壁层合箱梁的约束扭转进行了分析,给出了杆端内力的计算公式,并指出能量方法在解此类复杂问题时不易解出其精确解.
On the basis of geometric nonlinear analysis, considering various coupled effects, a theory of constrained torsion analysis of composite thin-walled box beams was developed based on the theory of composite laminated plates. Formula was presented about internal force. The results of analysis indicate that it's very hard to work out so complex question for energy method.
