Original Abstract

The contribution presents simulations of concrete fracture under high strain rates. For relatively low rates (below 0.1 m/s) rate dependency is attributed mostly to creep phenomenon, whereas for higher rates the leading phenomenon is inertia. Discrete meso-scale model is used to represent material behavior. Thanks to the explicit representation of mesoscale structure, the main inertia effects should be captured automatically. However, the inertia due to smaller omitted particles must be phenomenologically represented as a rate dependent component of the constitutive relation. In the presented study, several model parameters settings are investigated and the results of the numerical simulations are compared with the experimental evidence.
