颗粒材料在自然界和工程应用中极为常见,深入理解并合理利用其流变性对于预测与减轻自然灾害以及描述多种工程材料力学性质至关重要.然而,现有研究仍未建立起颗粒之间摩擦特性与颗粒集合体宏观的力学特性之间的物理联系.本文利用离散单元法(DEM)考察了不同颗粒间摩擦系数对定压剪切条件下的颗粒材料的流变性的影响,试图建立基于粒间摩擦的颗粒流变学模型.本研究计算显示,增加颗粒之间的摩擦系数可以显著改变颗粒集合体的整体流变特性,增加颗粒系统的有效摩擦系数µeff,并减小定压剪切条件下的稳态固体体积分数ϕs.在此基础上,本报告提出用于描述不同粒间摩擦特性颗粒材料流变性的无量纲数M,并建立摩擦流变模型.同时考察了M和无量纲颗粒温度Θ之间的关系,分析了摩擦系数对于粒间作用力概率分布函数的影响.进一步延伸了传统的流变模型的应用范围,有助于建立更为普适的颗粒材料本构模型.
