Rare earth resources in the weathered crust elution-deposited rare earth ore (WCEDRE-ore)
are mainly recovered by in situ leaching process. A new understanding of the engineering …

Ion-adsorbed rare-earth ores are mined using in-situ leaching, and their mechanical
properties significantly affect the efficient and safe recovery of rare earth elements. However …

Most geohazards and industrial processes are essentially gravity-driven dense granular
flows. Deep understanding of the effect of gravity on granular flow is of crucial importance in …

The essence of large deformation flow in loose geological bodies lies in the breaking and
rebuilding of force chains at the microscopic scale. Therefore, it is crucial to investigate force …

The application of the acoustic emission (AE) method for granular media has been
considered to be challenging and remains limited. Nevertheless, recent successful …

The force chain is the core of the multi-scale analysis of granular matter. Accurately
extracting the force chain information among particles is of great significance to the study of …

In this study, dynamic centrifuge model tests were performed for sand slopes under different
earthquake ground motions and slope angle to characterize the seismic performance of …

In this work, we numerically investigate the quasi-static shear behavior of ellipsoids under
triaxial compression using the level set discrete element method (LS-DEM). Assemblies …

The geological disasters caused by avalanche, large scale deformation, and flow slide of the
geo-granular materials have brought massive destruction and potential threats to national …

The present article proposes an evolutionary development of the photoelasticity method for
measuring stresses based on annular photoelastic sensors application along with stress …
