Parametric study of horizontally vibrated grain packings: comparison between Discrete Element Method and experimental results.

Numerical and experimental studies have been undertaken to analyze three parameters controlling the compaction of granular media submitted to sinusoidal horizontal vibrations. We have characterized the influence of the dimensionless acceleration
