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。

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.
