Parametric approach of target terms for structural fragments
The effects on the target terms for the structural fragments from the explosions of the cylindrical and spherical vessels were investigated using a parametric approach using Monte-Carlo simulations,to explore the characteristics of fragment impact and penetration into nearby facilities.The results showed that fragment rotation and lack of wind decreased the probability of impact within a given distance,but the rupture probability of the target was not affected by fragment rotation or wind.The probabilistic confidence intervals of fragment impact,and target penetration became narrower with the number of simulation runs,but the accuracy of the results increased.The probability of fragment impact increased with the volume of the target vessel and the degree of filling of the explosion vessel,but did not depend on the kind of explosion.The probability of target rupture increased slowly with the degree of filling of the explosion vessel,but was little influenced by the volume of the target vessel or the kind of explosion.
