oa True Tri-Axial Test Using Distinct Element Method

Many kinds of rock test for engineering properties have been carried out to obtain rock kinetic properties. However it is difficult to visualize inside rock specimen during laboratory tests. This study's objective is to reconstruct true tri-axial tests using Distinct Element Method (DEM). At first, tri-axial compression test is carried out to know correlations between analytical properties and rock properties obtained through compression test like cohesion and internal friction angle. Next, true tri-axial test is simulated using properties above. The result of the simulation, it was clarified that the simulation result can reconstruct a laboratory test qualitatively.
