Research project - Study of compaction bands due to grain crushing using breakage mechanics

Supervisor: Dr Giang Nguyen

Associate Supervisor: A/Prof Itai Einav

Localized compaction bands are narrow planar zones, formed within crushable granular materials or high porosity rocks under high confining pressures. The formation of compaction bands is usually associated with grain crushing, and porosity reduction of rocks or soils. This results in the permeability reduction of materials within the bands, which then act as fluid flow barriers. This problem has great economic importance to the extraction of oil or natural gas in the industry. Our study using constitutive models based on breakage mechanics theory (Einav, 2007), which has an intrinsic measure of the evolving grain size distribution, will provide insights into the physics of grain crushing and the formation of compaction bands.
