Statistical Estimation of Critical Stress Level of Explosive Materials Based on Percolation Theory
This paper discusses a statistical reliability/safety estimation model for several kinds of explosive materials. Especially, we analyze experimental results of a falling hummer test for explosives in order to estimate the critical stress level of the materials. In the literature, it has been known that the falling hammer test results seem to obey a Frechet distribution, but there still have been several issues for their estimation results. We focus on some resemblance between the explosion phenomena and the so-called percolation models, and try to derive a probability distribution under several assumptions inspired from the percolation theory. After the modeling, we show the statistical estimation results of the critical stress level by using our model, and compare to the ones by the Frechet distribution model in terms of goodness-of-nt and other aspects.
