Paper presented at the 48th U.S. Rock Mechanics/Geomechanics Symposium, June 1–4, 2014
Paper Number: ARMA-2014-7757
... Abstract The direct and Brazilian tension tests are the most popular methods for measuring the tensile strength of rocks. While the values of tensile strength obtained from these test are theoretically expected to be identical, the accumulated experimental data show that the direct tensile...

Paper presented at the The 42nd U.S. Rock Mechanics Symposium (USRMS), June 29–July 2, 2008
Paper Number: ARMA-08-188
... Method (FEM) analysis. This assumption is obviously improper for geomaterial numerical modeling. There are two reasons for the existence of the aforementioned ideas in people?s mind. Firstly, rock is always considered to fail under compression but under tensile stress. Secondly, tension test of rock...

Paper presented at the The 35th U.S. Symposium on Rock Mechanics (USRMS), June 5–7, 1995
Paper Number: ARMA-95-0471
... ABSTRACT: Micromechanical modeling analyses have been carded out to enhance our understanding of the effects of heterogeneity on the failure phenomenon in brittle rock. Uniaxial tension tests have been numerically simulated using the Dynamic Lattice Network Modek Micromechanical properties...
