Abstract:Over recent years, numerical simulations have arisen as the most effective method to analyze structures under blast events. However, in order to achieve accurate numerical predictions, reliable constitutive models contrasted against experimental benchmarks are needed. In this work, the experimental tests on normal and high-strength concrete slabs conducted by the University Missouri-Kansas City on the shock tube at the Engineering Research and Design Center, U.S. Army Corps of Engineers at Vicksburg, Mississippi, are modeled by using a novel constitutive model for concrete presented recently by the authors. The model makes extensive use of Fracture Mechanics considerations through the Cohesive Crack Model developed by Hillerborg and co-workers. The numerical predictions obtained show good agreement with the experimental results, especially in the case of the high strength concrete slabs.
