This paper will examine the applicability of the National Aeronautics and Space Administration (NASA) standard breakup model 2000 revision to explosion breakup in space. The cylinder specimens of stainless steel with smooth were explosively expanded to fragmentation. The driver was a column of the high explosive PETN inserted into the central bore and initiated by exploding a bundle of fine copper wires using a discharge current from a high-voltage capacitor bank. Expansion rate and the collection fragments will be analyzed based on the method used in the NASA standard breakup model 2000 revision to be compared with the explosion model adopted in the NASA standard breakup model. And this paper evaluated NASA standard breakup model 2000 revision model about size distribution, average cross-section area, area mass ratio distribution, delta velocity distribution.
