Blast-Induced Deformations of the Building Entrance Part Caused by Improvised Shaped Charges

Popis výsledku v původním jazyce

The presented results and discussion concern the behavior of a steel rectangular profile which can be found at the building entrances exposed to blast effect of military explosives. Currently, high explosives with liners are used to create armour-piercing charges to increase their effect. The article deals with the possible use of standardized TNT block demolition charges used in military practice to create improvised shaped charges to increase their penetrating effect in comparison with the concentrated or linear charges usually generated from this block demolition charges. The advantage of using the tested block demolition charges is their lower acquisition value in comparison with a special demolition charges and the speed of assembly of improvised shaped charges in field conditions. Several shaped charge types of different shapes have been designed. In the representative samples of designed shaped charge types, their effect on a structural element occurring was simulated, whereas the effect of explosive flow was further compared in these cases with simulations in the ANSYS software. The experiment performed in a live blasting area presented the effect of all charge types. The aim of the article was to verify the different effect of individual charge types on the structural element and to assess their penetrating properties. The results enable the determination of the further course of research in this area.
