(Particle Flow Code in 2 Dimensions; Particle Flow Code in 3 Dimensions) are programs for modeling the movement and interaction of assemblies of arbitrarily-sized circular (2D) or spherical (3D) particles. The particles are rigid but deform locally at contact points using a soft contact approach, in which finite normal and shear stiffnesses are taken to represent measurable contact stiffnesses.The particles may represent individual grains in a granular material or they may be bonded together to represent a solid material, in which case, fracturing occurs via progressive bond breakage. Solution by the distinct-element method allows dynamic stress waves to propagate through the particle assembly, which may exhibit slip or separation, with unlimited displacement, under the action of applied loading. Bonded assemblies...
