Description

<p>This study investigates the viscoelastic properties and the transition behavior between the liquid and solid of polyethylene beads dispersed in silicone oil and silicone oil-water mixtures, simulating the flow behavior of a layered structure consisting of iron ore and a coke bed with derived melts. Oscillation tests revealed that all samples exhibited elastic responses at small strains, transitioning to viscous responses at higher strains. Higher viscosity of silicone oil led to reduced strain at the onset of flow, indicating enhanced lubrication between solid phases. Creep tests showed minimal strain under low stress but significant strain increase over time at high stress, suggesting that the system can achieve a more fluid-like state over an extended period. These findings highlight the impact of liquid viscosity and phase fraction on the mechanical properties of complex multiphase systems.</p>
