【摘要】 基于植物秸秆纤维聚氨酯复合缓冲包装材料测试数据,首先拟合了参考密度的应力-应变曲线所确定的形状函数;其次考虑了材料密度、应变率影响因素,建立了复合包装材料的压缩本构模型,并利用实验数据成功识别了模型参数。结果表明,该本构模型和试验数据吻合性好,验证了材料压缩模型的可靠性,为解决植物秸秆缓冲包装材料的缓冲包装设计、有限元计算、深入研究缓冲性能及模型预测提供重要的理论依据。更多还原

【Abstract】 Firstly,the shape function under compared density is fitted based on the experimental data of plant straw texture compound material.Secondly,the compress constitutive relation is established considering material density,strain ratio and the parameters of the model are successful to identify.The correctness of model is proved by contrasting of calculated and experimental data.This research has provided important theory reference for the cushioning material package design,calculation of finite element and further study on cushioning property of plant straw texture material更多还原
