Exploring chemo-mechanics of granular material using DEM

Particle Size Distribution (PSD) is one of the prime guiding factors granular media response. Degradation via weathering a process, which brings about gradual shift in PSD. In nature, chemically sensitive material like calcite undergoes chemo-mechanical degradation bringing variations their behaviour. present study, an experimental investigation carried out to get insight into mechanical response during coupled process. The experiments were at two different rates dissolutions custom made 1D compression mould. From experiments, it clear that higher rate dissolution reduces lateral earth pressure more than lower rate. Discrete Element Method (DEM) analyses micromechanical process behind observed from experiments. results showed reduction stress as soon starts. DEM analysis confirms competing mechanism between grain size and rearrangement element for
