Sažetak
Modeling the change in the parameters of the soil exposed to the performance of the explosion, considering the heterogeneity of the soil, the dependence on the water content and the different calibration experimental parameters, is a challenge. The models, incorporated in the computer program Ansys 2020 R1 Autodyn 2D hydrocode, were used to model the performance of the explosive charge in the soil and can be used with certain accuracy to estimate the change in soil density in the environment of the explosive charge in an infinite environment. The processes of performance of three types of explosives on the density of the soil in the vicinity of the explosive charge and the influence of the mass of the ANFO explosive charge on the radius of the resulting expansion were modeled. The modeling results for cavity diameter are compared with the experimental data and presented in the article.
