Similarity of the Damage Functions for Ductile and Brittle Materials

The voids distribution function in ductile metal is derived theoretically in this paper, and verifications of the Fe and Ta recovered samples are made under dynamic loading. Their voids distribution is on the same curve, but the scales of voids number are different. This demonstrates their similarity. On the other band, from Ref. [5], the results of brittle material under static loading, also appear the same property. Thus, the author concludes that it is possible that all materials may have the same similarity. Finally, the prospects of using this property are discussed.
