The use of micro-concrete in reduced scale blast experiments

Popis výsledku v původním jazyce

This paper presents results of experimental program focused on the evaluation of the possibility of using reduced scale in blast loading experiments. The blast wave propagation can be easily scaled using Hopkinson Scaling Law so it is possible to scale the loading applied on a specimen. However the behaviour of a reduced scale reinforced concrete specimen is ruled by the material used to manufacture it. Based on experimental results of reduced scale specimens from standard concrete, a micro-concrete (a cement-based material with scaled-down aggregate) was proposed to improve the results. Experimental results are supported with finite element calculations using LS-DYNA software. Multiple methods of reinforcement modelling are proposed and discussed. The comparison of FEM analysis against results of the experiment brings a solid basis for understanding the behaviour of shock wave inside a specimen.
