In-plane Compressive Properties of Mild Steel Honeycomb Sandwich
摘 要
对普碳钢蜂窝夹芯板进行了面内压缩试验,利用贴片法测量了等效弹性模量和泊松比,测出了抗压强度.结果表明:不带面板时,蜂窝芯子的泊松比接近于1.0;带面板时,蜂窝板的泊松比减小到0.33~0.39,其值随面板厚度的增加而减小;等效弹性模量的实测值与计算值之间的相对误差小于7%;抗压强度的实测值与计算值之间的相对误差在0.6%~32%;面内压缩时,普碳钢蜂窝夹芯板的等效弹性模量及抗压强度主要受面板厚度和夹芯厚度的影响,二者均随面板厚度的增加而增大,随夹芯厚度的增加而减小,胞壁厚度和胞壁边长的影响很小.
Abstract
The Young’s modulus and Poisson’s ratio of steel honeycomb sandwich were measured by resistance strain gauge,and the compressive stress-strain curves were plotted.The results show that the Poisson’s ratios approached 1.0 for honeycomb core without facings,decrease to 0.33-0.39 for honeycomb panels with facings,and varies inversely with the face thickness.The errors of Young’s modulus between measurements and calculations are less than 7%,but the errors of peak compress strength reache 0.6%-32%.The Young’s modulus and peak compressive strength are influenced by face thickness and core thickness,both of them increase with face thickness and decrease with core thickness,but cell wall thickness and cell side length have little effect on them.
