A numerical study based on GBM3D-DEM model: Multi-level force chain analysis in dynamic flexural tensile strength test
The force chain network is the key information of rock materials under loading, which is close to the micro-scale cracking and macroscopic mechanical behavior of rocks. In this paper, a novel 3D grain-based mo...

Physical and dynamic mechanical behaviors of marble after heat treatment in quasi-vacuum and air-filled environments
The dynamic mechanical properties of rock specimens after thermal treatment in the air-filled environment (AE: i. e., at the free surface) have been extensively investigated, yet they are rarely estimated in t...
