... as it is created. Thus the area of new surface that can be created in a fracture episode should be limited by the amount elastic strain energy input before the fragmentation episode. We conducted laboratory and field (rock avalanche) measurements to test this assumption and consistently found more fracture surface...

... and is appropriately studied as a problem of ballistics and not aerodynamics. That is my first recollected experience in myth busting. My current efforts at myth busting also relate to masses of broken rock, one is the myth of fracture-surface energy, another is the myth of a fragmentation limit. 2 The myth...
