The idea that fracture and flow can be concurrent is slightly nontraditional. In the simplest of world-views, solids fracture but do not flow, and fluids flow but do not fracture. Observation of outcrops established long ago that this view is too simple; a single layer of rock can certainly show either behavior. But the question remains, Can one material do both? That is, can fracture and flow be “concurrent”? Is it not more correct to think that when a material flows it doesn’t fracture, and when it fractures, it doesn’t flow?
