| 摘 要： | 本文通过变分法用余能驻值原理对复合材料层合箱的弯曲应力，挠度及剪滞效应进行了分析，给出了相应的计算公式，并将其与文献1]2]中由最小势能原理所得的结果进行了对比分析。算例表明，三种计算结果基本一致，且与模型试验结果符合较好。

| Abstract: | In this paper, based on the principle of complementary energy, the formulas for calculating the bending stresses, deflection, and shear lag effect of composite laminated boxbeam were derived by means of the variational calculus. The comparison between numerical results of this paper and those of the References1]2] based on the principle of minimum potential energy is made which shows that the results are in good agreement. |
