摘要
本文对弹塑性蜂窝材料面内单轴加载时的平台应力及其对应的变形模式进行了理论分析。结果表明:当蜂窝材料胞壁抗弯曲能力提高时,一种新的变形模式一塑性屈曲有可能发生。对于理想弹性蜂窝材料,讨论了胞体几何形状及材料性能对蜂窝材料面内平台应力及变形模式的影响。
The platuea stresses of honeycombs and their corresponding deformationmechanisms are analysed under in-plane uniaxial loading condition. It shows that a newdeformation mechanism,plastic buckling,may occur when the bending resistability of cellis strong enough.The influences of geometry and material property of cell on the platursstresses and corresponding deformation mechanisms are discussed for elastic,perfectlyplastic materials.
