The further developed three-dimensional hybrid finite-discrete element method is then parallelized using...

... modelling. Based on the Brazilian Test [1] this paper analyses three types of rocks namely limestone, sandstone and shale, which belong to the sedimentary rock category with sandstone having greater strength than limestone and shale. The Finite Element-Discrete Element coupled method (FEM-DEM) used...

.... A servo–controlled uniaxial compression device with a constant displacement rate was used for loading and AE event-hit data was recorded continuously. Comparison of AE hit versus time for each type of tests shows two sharp steps in AE activity in UC tests and three steps in the Brazilian tests...

... ABSTRACT: In this study, static and dynamic tensile tests were carried out to study rock fracture mechanism. Brazilian test was adopted as the static tensile test with changing strain rates. while modified pipe test based on Hoppkins' effect was adopted as dynamic test. Vertical pipe test...

... ABSTRACT: The 3-D exact analytic solution by Wei & Chau (2001) was used to analyze the stress distributions within cylinders under the Brazilian test. By comparing the present solution with the classical 2-D solution by Hondros (1959), we found that, if the height-to-diameter ratio...
