Discrete element simulation of crushable rockfill materials
Water Science and Engineering, 2013 A discrete element method was used to study the evolution of particle crushing in a rockfill sample subjected to triaxial shear. A simple procedure was developed to generate clusters with arbitrary shapes, which resembled real rockfill particles.

AE Test of Calcareous Sands with Particle Rushing
Polish Maritime Research, 2017 The particle of calcareous sands was forced to crush, then the energy from the crushing was released by the form of sound waves. Therefore the AE technique was used to detect the calcareous sands AE signal when it crushed.
