关于蜂窝结构面内剪切模量的注记

Note on In-plane Shear Modulus of Honeycomb Structures

本文指出Gibson等提出的等壁厚峰窝结构在面内剪力作用下的单元分析不满足平衡条件.本文建立了等壁厚与非等壁厚峰窝结构在面内剪力作用下的合理的单元分析,导出了蜂窝结构面内折合剪切模量G_(xy)的计算公式.本文结果与实验数据符合得很好.

In this paper, it is pointed out that the element analysis, developed by Gibson et al, of honeycomb structures with walls in uniform thickness under in-plane shear load does not satisfy equilibrium conditions. A reasonable element analysis of honeycomb structures with walls in uniform thickness or nonuniform thickness is established. A converted formula for in-plane shear modulus G_(xy) of honeycomt structures is derived. The results in this paper coincide well with experimental data.
