摘要
A comprehensive study of the rheological properties of granular materials is essential for predicting and mitigating natural disasters.Man et al.[1]developed a theoretical model of rheology for spherical granular materials,which incorporates inter-particle friction,inertia numbers,and particle temperature.The rheological model is of great significance for establishing a more general constitutive theory of granular materials and an in-depth understanding of the micro-topology of complex granular systems.
