This paper aims to clarify the fracture phenomenon of a closed steel vessel generating a lot of random fragments by high internal pressure due to charge explosion. For this purpose, a fracture model based on the distribution of effective work required for individual fragment formation was established to estimate the fragment weight distribution, and the vessel wall strain rate at fracture was calculated. The interrelation between these two factors was examined by the fracture test of the vessel with such a high fracture strain rate, as an order of 10^4 per second. It was confirmed from the test results that the fragment weight distribution is explained well by the fracture model proposed and the distribution characteristics q_0, q_m and β are the functions of fracture strain rate, namely the external force imposed to the vessel. Their empirical equations are presented, which will be analyzed theoretically in the next report.
