Paper presented at the Gulf Rocks 2004, the 6th North America Rock Mechanics Symposium (NARMS), June 5–9, 2004
Paper Number: ARMA-04-480
... ABSTRACT: The description of the behavior of rock masses is usually based on the behavior of intact rock samples studied in the laboratory. One of the difficulties in describing the rock mass behavior is assigning the appropriate constitutive model. With the progress in discrete element...
