【摘要】 为了建立蜂窝纸板本构模型,通过实验方法得到其应力—应变曲线,根据提出的确定三次Bezier曲线特征多边形的方法,求得拟合曲线,通过比较总偏差与设定阈值的大小验证拟合曲线和实验曲线的拟合度。结果表明,拟合曲线和实验曲线有很好的拟合度,用三次Bezier曲线参数方程分段表示蜂窝纸板的本构模型是可行的。更多还原

【Abstract】 In order to establish the constitutive model of honeycomb paperboard,the stress-strain curve of honeycomb paperboard was obtained by experimental method.The fitting curve was obtained according to the method of determining the characteristic polygon of cubic Bezier curve.And the fitting degree of the fitting curve and the experimental curve was verified by comparing the total deviation with the set threshold.The results showed that the fitting curve and the experimental curve has good fitting degree.It is feasible to sectional represent the constitutive model of honeycomb paperboard with cubic Bezier curve equations.更多还原
