Compressibility of granular fluids
WebJun 26, 2016 · This phase separation is triggered by a negative compressibility. The control parameter is the restitution coefficient; at low dissipation, the effective pressure is a monotonically increasing function of density, whereas for larger dissipation a decreasing pressure as function of density is observed. ...

WebIt is characterized with low unit weight, high shear strength and low compressibility and finds a major application as an alternate material in the geotechnical engineering applications. However, some coal ash fills are susceptible to wetting-induced collapse due to the loss of capillary suction which stabilizes the inter-granular bonds.
