In the present work, a model describing the phenomena of initiation of detonation in condensed explosive by a shock wave is proposed. The model is adjusted to the system corresponding to the so-called wedge test, which is used for determination of the shock sensitivity of explosives. The system is described, the problem of initiation is formulated and the method of solution of the problem is presented. The results of modelling are compared with the wedge test data given in literature. It is proved that the model proposed can be applied for determination of the rate of chemical decomposition of explosives (the so-called macrokinetic equation).
