Flat-joint model to reproduce the mechanical behaviour of intact rocks

The mechanical behaviour of intact rock materials is controlled by properties of grains and cementation (bonding) between grains. In the particle flow code (PFC), three main bonding approaches namely contact bond (CB), parallel bond (BP) and flat-joint (FJ) models have been used for simulation of bond between particles. This article firstly investigates the ability of these bonding approaches in reproducing the mechanical behaviour of intact...
