A 3-dimensional discrete element method model has been developed to simulate static and dynamic rod penetration test in a calibration chamber. The chamber has been filled with a scaled analogue of Fontainebleau sand. Crushing effects on penetration results have been examined. It has been found that particle crushing reduces penetration resistance for both static and dynamic tests. Microscale observation of crushed particles has been conducted. It is shown that dynamic impact causes more crushing events. The crushed particles are distributed within 2–3 radius from the rod for both tests.
