Název v původním jazyce

Influence of basalt mesh induced by increase of heterogeneity of cement composites on its resistance under near-field blast

Popis výsledku v původním jazyce

This paper describes the influence of multiple basalt meshes in cement composite specimens with dispersed fibers on a damage induced by a near-field blast. Experimental measurements performed in the Boletice military area in 2014, 2015 and 2016 are evaluated by numerical simulations. The evaluation of the results is mainly focused on the stress in the cement composite with dispersed fibers, propagation of the overpressure caused by the blast and velocity of the ejected parts from the specimen. The influence of velocity of ejected parts coming out of the specimen, originaly caused by the impact of a steel plate which bears TNT charges, is examined. And last but not least, the influence of presence and position of basalt meshes in the specimen on its damage induced by delamination is also examined.
