Abstract

In this work we present several statistical analyses about research on the subject of granular materials during the last ten years. These statistics are based on the set of articles published in the Granular Materials section of Physical Review E during this period, comprising roughly 1000 documents (including rapid communications). We estimate the degree of contribution of countries, academic institutions, authors, and articles, in terms of the frequency of appearance on the articles’ affiliations and the number of citations. On the first hand, these analyses serve as a recognition to researchers and research communities that have notably contributed to the development of knowledge on granular materials. On the second hand, the presented statistics allow for identifying countries and institutions where research in granular materials is the most developed, and also places where it can be developed in the future. Finally, these analyses allow for highlighting which cooperations amongst countries have been the most active during the last decade, which in turn allows for identifying potential links to be created and developed across this research network.
