2025-09-19 Data set for "Development and Validation of Two-Layer Material Point Method for Debris Bed Formation Behavior in Severe Accident of Sodium-cooled Fast Reactor" doi:10.57760/sciencedb.28259 en There are 8 figures submitted in the paper. Fig.1 shows the schematic illustration of information transfer between grid and particles in MPM (made by the drawing software). Fig.2 shows the schematic illustration of flowchart of Two-layer MPM (made by the drawing software). Fig.3 shows the schematic illustration of the geometry of experiment and simulation (made by the drawing software). Fig.4 shows the snapshot from experiment[28], the snapshots from simulations. Arrows in experiment are from the referenced paper[28]. Arrows in simulations are added by drawing software. Fig.5 shows the definition of the base angles of debris bed shape and debris bed height (made by the drawing software). Fig.6 shows the bed height comparison between experiment[28] and our simulation. Fig.7 & 8 shows the debris bed base angle and debris bed height comparision. Black point are from experiments[28], red points are from simulation results.
