A DEM study of oedometric compression of model granular materials Initial state influence, stress ratio, elasticity, irreversibility.
A DEM simulation study of spherical beads with elastic-frictional contacts in oedometric compression is carried out for a wide variety of initial states, differing in solid fraction Φ, coordination number z (independent of Φ in dense systems) and inherent anisotropy. Stress ratio K0 = σ2/σ1, along w...
