Study on U-shape Zero Poisson's Ratio Honeycomb Core Equivalent Elastic Modulus

零泊松比蜂窝夹层具有独特的变形特性,适用于一维柔性蒙皮。蜂窝夹层结构等效弹性模量的研究是夹层结构设计的基础。文章在梁模型的基础上,用能量法推导了蛇形环零泊松比蜂窝芯的等效弹性模量理论公式,并将理论公式与有限元法计算结果进行了对比,验证了理论公式的正确性。

Zero Poisson＇s ratio honeycomb core, which adapt to one-dimensional flexible skin, has unique de- formation characteristics. And its equivalent elastic modulus is the basic of engineering design. In this paper,the e- quivalent modulus formulas were derived based on beam model in energy method; the formulas＇s result was compared with finite element method results.
