“…It is generally corresponds to the experimental data [4]. However, quantitative comparison of the values of concrete strength has shown a significant difference between the results of the numerical simulation and the experimental data [4][5][6]. Figure 3 shows numerically obtained dependences of the compressive and tensile strength on strain rate for uniaxial compression and tension tests of zirconium alumina concrete samples.…”

In the present paper the multiscale approach to the construction of rheological models of brittle materials with heterogeneous internal structure is implemented within the numerical method of movable cellular automata. An example of application of the implemented approach to determine the mechanical properties (including parameters of the rheological model and strength) of brittle materials with complicated internal structure at both macroscopic and mesoscopic scales is described. The effect of strain rate on brittle materials behavior under uniaxial compression and tension is analyzed

“…The high-performance fiber reinforced concrete, CARDIFRC, developed and produced at Cardiff University (Benson & Karihaloo, 2005a,b;Benson, Nicolaides, & Karihaloo, 2005) was tested using the Hopkinson Split Bar (HSB) equipment (with steel bar diameter 20 mm) (Akopov et al, 2003). Standard Brazil tests were conducted on circular discs of CARDIFRC (diameter 15 mm and thickness 10 mm).…”

“…However according to the criterion of incubatory time, dynamic strength is characterized by the incubatory time, but not the maximum stress. For simplicity of understanding, we consider simple test methods, such as the split Hopkinson bar test (the Kolsky method) [10][11][12] and the spall test [13]. Such tests allow to carry out calculations in one-dimensional statement.…”

When we want to compare the strength of two materials, we compare the table values of quasistatic strength. However results of some experiments show that the strength ratio of the materials can change with increase in rate of loading. Such "substitution effect" of material strength at different strain rates is studied in this paper. It is shown that one material can have a lower dynamic strength for a higher static strength compared to the other material. Tests of two different materials, tests of mortar and concrete, and tests of concrete with different water content are considered. It is shown that load-carrying capacity of materials and the substitution effect of material strength in a wide range of loading rates can be predicted by the incubation time criterion.
