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.
