Experimental and Numerical Analysis of Impact Strength of Concrete Slabs

The topic of this paper is experimental and numerical analysis the impact strength unreinforced concrete slabs. Impact significant in case some accidental loads during exploitation. can be determined experimentally, using Drop-weight test, Charpy Projectile Explosive etc. In research, a model for determining slabs based on Finite element method (FEM) high-end engineering software has been proposed. Modelling approach to problem was applying Explicit dynamics FEM analysis. Thereat, two different existing material models were enforced: Concrete damage plasticity – CDP (implemented ABAQUS/Explicit software), Riedel-Hiermaier-Thoma RHT ANSYS Workbench software). Analysis parameters both models, necessary as input data, have through series analyses validated by performed experiments, drop-weight test. Results compared with ones, well mutually. Advantages drawbacks are highlighted, reliability proposed models. FE confirmed successfully used further research.
