Mechanics of binary and polydisperse spherical pebble assembly

Mechanics of a crushable pebble assembly using discrete element method

“…4b. Furthermore, the residual strain after unloading is large for loosely packed assemblies for a given damage criterion as also observed in the previous studies [6,10]. Hence, in the present study, we observe a significant influence of the initial packing factor in addition to the influence of the damage coefficient in the unloading stage.…”

“…4a. In addition, the average normal force is varying as a liner function of hydrostatic pressure as reported in previous studies [6,10]. Fig.…”

Size-Dependent Crush Analysis of Lithium Orthosilicate Pebbles

“…It has also been shown that the pebble bed thermo-mechanical behaviour is strongly influenced by the individual pebble interactions and their packing structure in addition to the bulk material properties of the pebbles. [13][14][15][16][17] The fabricated OSi pebbles have a size distribution and the size distribution has not been taken into consideration in the previous numerical studies except in (Ref. 15).…”

“…[13][14][15][16][17] The fabricated OSi pebbles have a size distribution and the size distribution has not been taken into consideration in the previous numerical studies except in (Ref. 15). The effect of pebble size distribution on the macroscopic behaviour has been studied using a polydisperse pebble assembly through Discrete Element Method (DEM) (Ref.…”

“…The effect of pebble size distribution on the macroscopic behaviour has been studied using a polydisperse pebble assembly through Discrete Element Method (DEM) (Ref. 15). However, the study was focused on a non-crushable pebble assembly.…”
