Notes:
Numerous distributions (Mott, exponential, bimodal) have been proposed on the basis of geometrical or semi-empirical grounds as suitable for characterizing the mass distribution from fracture or spallation. It is argued here that the lognormal distribution is particularly suitable on the basis of a number of considerations: empirical fits, the fractal character of fracture, and the geometrical arguments when carried to their logical conclusion. We explain the deviations from the lognormal distribution as due to the finite thickness of the shell, which violates the scale-independence requirement for exact fractal behavior and introduces multifractal character to the spallation process. A plausiblity argument for the observed relationship between ductility and the shape of the distribution is offered.
