A grain-based distinct element model is used to reproduce the laboratory response of both intact and granulated Wombeyan marble. The term “granulated” refers to a heat treated marble where the cohesion of grain boundaries has been destroyed. The unconfined compressive strength granulated marble is less than 50% of that of intact marble, while the strength of the granulated marble increases to...
