| 摘 要： | 瓦楞纸板因其可降解及优良的缓冲性能,常用于运输包装中。用万能试验机得到了B楞瓦楞纸板的静态应力-应变曲线,再用最小二乘法拟合出了此纸板的静态本构关系。然后,根据所拟合的曲线,计算出了B楞瓦楞纸板的缓冲系数-最大应力曲线。最后,给出了一个B楞瓦楞纸板的承载算例。

| 关 键 词： | B楞瓦楞纸板 应力-应变曲线 缓冲曲线 |

| Abstract: | Because of its degradable and excellent cushioning properties,corrugated paperboard is commonly used in transport packaging.The strain-stress curve of corrugated paperboard with B-flute was obtained by quasi-static compression experiment.The constitutive relation was fitted using least square method.Then,according to the fitting curve,the cushion coefficient-max stress curve of corrugated paperboard with B-flute was calculated.At last,an example of the paperboard bearing calculation was given. |

| Keywords: | B-flute corrugated paperboard stress-strain curve cushion curve |
