Discrete Element Method for Mechanics Properties and Size Effect Analysis of Granite
Abstract:
The mechanics models formed by packed circular discrete elements and randomly distributed in a specified region were used to investigate the mechanics properties of granite, and some different sizes of discrete element models were carried out to study the size effect of mechanics properties. The simulation results suggest that there is no obvious size effect for Poisson’s ratio, compressive strength and Young’s modulus. However, the value of bending strength decreases with the increasing of the model size.
