摘要：

The report analyzes the results of the experimental-theoretical investigation of the response of brittle media (fine-grain concrete, fiber-reinforced concrete, ceramic brick, gabbro-diabase and limestone) to dynamic loading. To determine the properties of the studied materials under dynamic strain rates, the traditional Kolsky method using Split Hopkinson Pressure Bar (SHPB) and its modification, the 'Brazilian test', were used. The theoretical interpretation of failure was based on the theory of incubation time of failure developed in the works by N.F. Morozov and Yu.V. Petrov. All the tested materials demonstrate a qualitatively similar character of failure. Copyright (C) 2017 The Authors. Published by Elsevier B.V.
