In many geotechnical problems soil grading is not a fixed quantity but an evolving one. Constitutive models have been designed to accommodate this, bu they need to be fed with reliable experimental work. Such experimental work is particularly difficult when crushing is the driving mechanism of grading evolution. A reasonable alternative may be found by using the discrete element method (DEM). The talk presents a DEM model designed to do that and illustrates its performance with result from elementary test simulation as well as (virtual) calibration chamber testing.
