title = "A bonded particle modelling for rock material",
abstract = "Bonded Particle Method (BPM) has recently been extensively used to simulate brittle materials. In BPM, brittle material gets represented as a dense assemblage of particles (grains) connected together by contacts (cement). Only particle motion law and contact constitutive model are therefore needed to perform the simulation. BPM does not require complicated plasticity constitutive laws, but it seriously depends on the contact micro-properties. Therefore a calibration process is needed to establish a unique set of these micro-parameters. In this research, discrete element code of UDEC is employed to apply BPM. This code can create random-shaped and non-uniform-sized particles interacting in frictional and cohesive contacts. Using this approach, contact micro-parameters are calibrated to fit the conventional test results (uniaxial and triaxial compression, and Brazilian tension).",
