MODELS FOR ROCK FRAGMENTATION EMPHASIZING CLUSTESR
ON CORRELATED DIMENSION INTERVALS
(Abstract)
The paper approaches the problem of modeling fragmentation phenomena from
the point of view of the multimodal size distributions of fragments that were
found experimentally. Dichotomic and polytomic recursive models are introduced
and discussed, including their possible links to material parameters. The predictions
of the models are in good agreement with the experimental observations and
offer hints for future experimental investigations. The lack of general consent
regarding fragments clustering on certain size intervals is explained in terms
of the different approaches which have been used, the discussion being illustrated
by concrete examples.
Key words: fragmentation, multimodal distributions, dichotomic models, polytomic
models, entropy, specific surface energy.
