Type: article
Abstract: This article is devoted to the modeling of the stress-strain diagram of compressed concrete under the action of dynamic loads of various intensities. The main attention is paid to the influence of the strain rate of concrete on the determining parameters of this diagram. The degree of dependence of the dynamic increase factor (DIF) and the level of critical deformability of compressed concrete both on the rate of its deformation and on the level of elastic-plasticity (class) has been established. The analytical relationship between the main static and dynamic characteristics of the deformation diagrams of compressed concrete is established using the hypothesis of invariance and independence from the load mode of the specific potential energy of the ultimate deformation (destruction) of the material.
