论文摘要
我们通过数值研究具有不可逆转的吸引人相互作用的致密湿颗粒颗粒的机械和几何特性。随着填料的增加，剪切模量显示出两个拐点，并且大容量模量显示出非单调的行为。配位数还显示了两个拐点。配对相关函数中的峰位置由于吸引人的相互作用而转移到较低的值。粒子构型的Voronoi镶嵌物表明，随着包装分数接近干扰点，Voronoi细胞体积的概率密度函数扩大。
We numerically investigate the mechanical and geometrical properties of dense wet granular particles with irreversible attractive interaction. The shear modulus exhibits two inflection points as the packing fraction increases, and the bulk modulus shows a non-monotonic behavior. The coordination number also exhibits two inflection points. The peak position in the pair correlation function shifts to a lower value due to attractive interaction. The Voronoi tessellation of the particle configuration reveals that the probability density function for the volume of the Voronoi cell broadens as the packing fraction approaches the jamming point.
