摘要
纸蜂窝面外压缩临界应力是评估纸蜂窝承压性能的一个重要指标。试验分析表明Gibson多孔材料屈曲应力评估方程适合于纸蜂窝的压缩承载性能评估。通过数据拟合的方法找到了适合于纸蜂窝面外压缩临界应力与纸蜂窝相对密度之间的关系,该评估方程可用于纸蜂窝结构的合理选用和优化设计。
Critical compression stress is an important index to evaluate the compression properties of paper honeycombs. Experiment analysis showed that Gibson＇s evaluation equation of cellular materials can be used to paper honeycombs. Fitting the experiment data to the equation can obtain the relationship between the critical compression stress and the relative density. The evaluation equation can be used to select and optimize.paper honeycomb structure.
