Minimal fragmentation of regular polygonal plates
Abstract
Minimal fragmentation models intend to unveil the statistical properties of large ensembles of identical objects, each one segmented in two parts only. Contrary to what happens in the multifragmentation of a single body, minimally fragmented ensembles are often amenable to analytical treatments, while keeping key features of multifragmentation. In this work we present a study on the minimal fragmentation of regular polygonal plates with up to 100 sides. We observe in our model the typical statistical behavior of a solid torn apart by a strong impact, for example. We obtain a robust power law, valid for several decades, in the small mass limit. In the present case we were able to analytically determine the exponent of the cumulative probability distribution to be ½. Less usual, but also reported in a number of experimental and numerical references on impact fragmentation, is the presence of a sharp crossover to a second powerlaw regime, whose exponent we found to be between ⅓ and 1 depending on the way anisotropy is introduced in the model.
