摘要：

The paper reports granular dynamics simulations of a dense spherical agglomerate consisting of a random polydisperse system of autoadhesive particles impacting orthogonally with a target wall. A range of impact velocities has been examined which resulted in rebound, fracture or shattering depending on the magnitude of the impact velocity specified. Visualisations of agglomerate breakage are presented together with data on the evolution of the target wall force, the kinetic energy of the agglomerate, the number of bends broken and the amount of debris detached during a collision. The evolution of the processes preceding agglomerate breakage is also discussed.
