The Influence of Grain Size Distribution on Mechanical Compaction and Compaction Localization in Porous Rocks

Résumé

 Increasing the polydispersivity of the grain size distribution decreases the stress required for inelastic compaction.  Compaction localization is inhibited in synthetic samples with a bimodal polydisperse grain size distribution.  A transition from compaction localization to delocalized cataclasis is observed for samples with very polydisperse grain size distributions.
