    Abstract

    This paper discusses different techniques for the experimental estimation of the static and dynamic internal friction coefficients of fragmented ceramics. These were applied to the powders of two ballistic ceramics, SiC and Al2O3. The relationship between the fragment sire and the internal friction coefficients of the powders was determined. The results obtained with the different techniques are compared.
