Summary:The paper presents the numerical and experimental study of the behavior of porous reactive mixtures (Al-S and Al-Tf) under explosive loading using a multicomponent medium model. The initial dispersion of the reactive mixture is varied to evaluate its contribution to the fracture of the cylindrical ampoule. The results have shown that the high rate of heat release during the chemical reaction in the bottom part of the ampoule and a sharp increase in pressure lead to the formation of the gas phase, which causes the ampoule fracture. It is found that the higher the initial dispersion of the mixture components is, the more intensive the ampoule failure is.
