Live in-person introductory training course. This four-day course provides guidance in the use of the Itasca codes PFC2D and PFC3D to simulate the mechanical behavior of granular and solid materials.
Version Notes:FLAC 8.0
Level: Intermediate Runs in Demo: No
FLAC is applied to study the behavior of progressively collapsing pillars. The effect of backfill confinement is evaluated by comparing different scenarios: no backfill, tight backfill and backfill with a 10 cm gap between the backfill and the roof. The peak/residual strength of the pillar is simulated using the strain-softening material model in FLAC, and the pore-collapse behavior of the backfill is simulated using the double-yield material model.
