Abstract
Various packing methods such as vibration, shaking, etc, in addition to normal gravitational settling, and be often used to densify powder compacts. Many issues relevant to this matter are of great importance in advanced ceramic powder processing. In the present work, the relaxation of structure due to vibration is addressed by using a computer experimental model based on Monte Carlo method. Packing structures, diffraction patterns, radial distribution functions are used for the characterization of structures. Bulk properties such as packing fraction and average height of the deposit are examined. The results agree well with those observed in model experiments, even with more implication.
