A Hybrid Method On Modeling Of Grain Crushing Tool

The mechanical behaviors of gravelly sands are greatly affected by the morphology and size of gravel grains. In this paper, a systematic approach that integrated computational geometry was proposed to simulate gravel grains with different angularity and aspect ratio in discrete element method (DEM) modeling.

Investigating The Influences Of Indentation Hardness And ...

In addition, the rock crushing models were calculated using a discrete element method code, i.e., Particle Flow Code in two dimensions (PFC2D). PFC2D is widely used in the simulation of rock crushing behaviors [4, 6, 21]. In this paper, the crushing models are calculated based on the UCS and BTS of the rock-like specimens.

Numerical modeling study was carried out by finite difference method (FDM). In this method, the whole domain was discretized into small two-dimensional zones (elements) that were interconnected with their grid points (nodes) (Naylor, 1982; Soren et al., 2014). Over each zone, the differential equation of equilibrium was approximated.
