The Suitable Discretization of Concrete Plate Finite Element Model Exposed to High Velocity Loading

Popis výsledku v původním jazyce

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 plate 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. Non-linear material model of concrete, continuous surface cap model, has been used to capture the concrete behaviour. Influences of various discretization features on the final results (crack patterns, vertical deflection) are being monitored, compared with physical experiment data and discussed.
