Original Abstract

The aim of this paper is the verification of the behavior of nonlinear concrete material models subjected to dynamic loading. The behavior of five selected nonlinear concrete models is tested within numerical simulations of the testing of the mechanicophysical properties of concrete in uniaxial and triaxial compression, using cylinders. These numerical simulations are performed using the explicit finite element approach and their results take the form of load-displacement and load-time diagrams created for a concrete cylinder under dynamic compressive loading whose behavior was calculated by individual nonlinear models of concrete. The results gained from the numerical simulations are compared with experimental results obtained from laboratory tests performed for the purpose of verifying the nonlinear concrete models. This comparison shows the differences in the behavior of the individual nonlinear models of concrete and the approximations of the experimental data. The comparison allows conclusions to be drawn as to which nonlinear models provide the best approximation of the test data, and therefore which models best describe the behavior of the tested concrete in compression.
