Fragment Size Distributions From The Dynamic Fragmentation Of Brittle Solids

摘要

Experimental and theoretical size distributions resulting from dynamic fragmentation are briefly surveyed. The power-law character unique to brittle solids is contrasted to fragment distributions of other materials. The catastrophic fracture of competent brittle solids is shown to have close parallels to hydrodynamic turbulence in fluids. Ideas that emerge from the physical similarities suggest methods for extending an earlier energy-based theory of dynamic fragmentation. Features of this theory are compared with limited fragmentation data for brittle solids.
