FEM-DEM simulation of Uniaxial Compressive Strength (UCS) laboratory tests [PDF]

REM: International Engineering Journal, 2020
Finite/discrete element methods (FDEM) are hybrid numerical models that use algorithms to analyze the transition from continuous to discontinuous. This type of formulation allows modeling physical laboratory tests with greater proximity to reality.

Prediction of strength and deformability of an interlocked blocky rock mass using UDEC [PDF]

Journal of Rock Mechanics and Geotechnical Engineering, 2017
The accurate prediction of strength and deformability characteristics of rock mass is a challenging issue. In practice, properties of a rock mass are often estimated from available empirical relationships based on the uniaxial compressive strength (UCS).

Loading rate effect on the uniaxial compressive strength (UCS) behavior of cemented paste backfill (CPB) [PDF]

Construction and Building Materials, 2021
Underground mined-out areas and tailings are the two major harmful consequences from metal mining industry. Cemented Paste Backfill (CPB) method, refilling the tailings back to the underground mined-out areas, has been widely used worldwide. Clear understanding on the uniaxial compressive strength (UCS) behavior of the CPB is very important for the ...

Support Vector Machine (SVM) Application for Uniaxial Compression Strength (UCS) Prediction: A Case Study for Maragheh Limestone

Applied Sciences, 2023
The geomechanical properties of rock materials, such as uniaxial compression strength (UCS), are the main requirements for geo-engineering design and construction. A proper understanding of UCS has a significant impression on the safe design of different foundations on rocks.

Experimental Study of Uniaxial Compressive Strength (UCS) Distribution of Hydraulic Backfill Associated with Segregation [PDF]

Minerals, 2019
Stope backfilling with mine wastes has become a common practice in underground mines worldwide. Despite the increasing popularity in paste and rock fills, hydraulic fill made of classified mill tailings or sands remains commonly used in many mines. When such a slurried material is placed in a mine stope, a phenomenon known as segregation can take place
