Original Abstract

The article deals with the analysis of the dynamic behavior of a~concrete structural element during fast dynamic processes. The constitutive material model must be chosen appropriately so that it takes material viscosity into account when describing the behavior of material. In this analysis, it is necessary to use fairly complex viscous material models which can affect, for example, vibration damping and the dependence of strength or even of the entire stress-strain curve on the strain rate. These relatively complex models are often formed via the combination of viscoelastic models with viscoplastic models or viscous damage models. Numerical simulations are performed for these models. The numerical analysis is validated by experimental measurements.
