Originální abstrakt

Numerical approach using the FEM has been used to model the behaviour of the reinforced concrete specimen subjected to the pressure blast wave. The concrete structure is a slab freely supported around the perimeter by a steel plate and a concrete base. A simplified 3D blast model has been used, which involves the pure Lagrangian approach of FEM. The analyses have been conducted using explicit solver. 3 different non-linear material models of concrete have been used to capture the concrete behaviour: CSCM (Continuous surface cap model), Schwer Murray continuous surface cap model, and JHC (Johnson-Holmquist-Cook) material model. Influences of various mesh sizes on the final results (crack patterns, vertical deflection, strain-time dependence) are being monitored, compared with physical experiment data and discussed.
