This paper proposes a statistical model of critical stress value based on an analysis test results of falling hammer tests for three kinds of explosives. Logistic distribution and three extreme distributions are considered as the candidates of the statistical models, and are compared their adequacy using Akaike's Information Criterion (AIC). The explosives tested are RDX, PETN and Picric Acid, which can be regarded as typical chemicals of nitramines, nitrates and aromatic nitro compounds, respectively. The TypeII maximum extreme distribution(Frechet distribution) is found to be the most appropriate model to represent the relationship between the probability of explosion and the stimuli in the falling hammer test.
