La dimension fractale et l'étendue granulaire comme paramètres d'identification des mélanges granulaires
Abstract The aim of the survey presented herein is to check whether the couple “fractal dimension-granular range” (DF, d/D) may be used as an identification parameter of a grading curve and therefore of a granular mix. Some granular mixes, for which the distribution of the grains is perfectly fractal, have been made up. Each granular mix has been identified by the fractal dimension (DF) in and by the granular range. Some tests have been conducted to determine experimentally the porosity. The porosity values are expressed in terms of the product of the two following parameters – fractal dimension and log(D/d), that is DF.log (d/D). The results show the relevance in using this couple since it is able to identify the granular mixes and to describe the development of the porosity value (compacity) according to a given way and seemingly the ability to point out the same optimum value of the fractal dimension that corresponds to the minimum porosity which, in fact, is the value that corresponds to the topological dimension of a volume, ie 3.
