Annotation: In the work, by means of a computer simulation technique, the features of the impact interaction of cylindrical steel impactors with concrete, reinforced concrete and steel fiber concrete plates in the range of velocities of 100-800 m/s are investigated. A comparison of experimental results with the data of mathematical modeling of impact interaction of steel cylinders with concrete slabs is given. To implement the model, the «RANET–3» software package was used, designed to solve impact and explosion problems in a full three-dimensional formulation, modified to solve dynamic problems by the finite element method. Dynamic fracture in concrete is considered as a process of growth and fusion of microdefects (cracks, pores) under the action of stresses generated during loading. The paper generalizes the model of deformation and fracture of fine-grained concrete under shockwave loading on steel fiber concrete.
Keywords: steel fiber concrete, shock loads, mathematical model, shock wave loading, reinforced concrete, concrete, dynamic destruction.
