An approach to obtain analytical closed-form expressions for the macroscopic 'buckling strength' of various two-dimensional cellular structures is presented. The method is based on classical beam-column end-moment behaviour expressed in a matrix form. It is applied to sample honeycombs with square, triangular and hexagonal unit cells to determine their buckling strength under a general macroscopic in-plane stress state. The results were verified using finite-element Eigenvalue analysis.
本文提出了一种获取各种二维蜂窝结构宏观“屈曲强度”解析闭式表达式的方法。该方法基于以矩阵形式表示的经典梁柱端弯矩行为。将其应用于具有方形、三角形和六边形单胞的蜂窝样本，以确定它们在一般宏观面内应力状态下的屈曲强度。结果通过有限元特征值分析进行了验证。
