Abstract

软物质系颗粒材料的物理和力学行为是当前多学科交叉研究的热点之一，探究形状、粒径等几何因素对颗粒材料填充和力学性能的影响具有重要的科学意义。特别是对具有复杂形状的颗粒材料，由于其微结构的各向异性，以及颗粒间高度非线性的离散力学作用，对颗粒胞元的准确描述以及选择高效的数值计算方法是模拟研究材料填充和力学性能的关键。我们分别采用改进的松弛算法、蒙特卡洛方法和离散单元法，系统性研究了一类非凸形状颗粒材料填充密度、微观排列结构和在双轴压缩下的力学性能，构建了其在二维条件下的最密填充结构及填充率的解析表达式。并通过解耦颗粒形状和尺寸因素，建立了复杂形状颗粒材料混合填充率和在压缩条件下力学性能的预测公式，为这类低密度自稳定颗粒材料的工程应用提供理论指导。
