Fe-modeling of fibre reinforced concrete slabs subjected to blast load

Fiber reinforced concrete elements are used as protection against blast loads and fragments. The present project is aiming at an accurate FE-modelling of the behavior of such elements loaded by transient dynamic loads. Thus blast experiments on thin slabs, hard and soft impacts on beams of different sizes with and without fibres, form the basis of experimental results. The codes used are LS-DYNA and ABAQUS/Explicit with various material models, e.g. the ''Winfrith'' concrete model for LS-DYNA and the ''Constitutive model for brittle cracking'' in ABAQUS/Explicit. In the present paper the experimental results from blast loads on slabs are presented with results from some FE-simulations.
