on Blast Pressure analysis due to a partially confined explosion iii afterburning effect
International Journal of Protective Structures, 2012Co-Authors: Idan E Edri, V.r. Feldgun, Y S Karinski, D Z YankelevskyAbstract:This paper aims at extending our understanding with regard to some characteristics of an interior explosion within a room with limited venting. An interior explosion may be the result of an ammunition storage explosion, or an explosive charge as part of a terrorist action or a warhead explosion that follows its penetration into a closed space in a military action. Full scale experiments have been performed with a TNT charge detonated at the center of a single room sized space with rigid boundaries. The room has a limited size opening for venting at the ceiling. Numerical simulations of the problem have been performed using AUTODYN Ver. 12.1 and compared with the experimental measurements. Some deviations between the measured Pressure and the predicted Pressure motivated the present study in an attempt to study the effect of the additional energy released due to the burning of the detonation products reacting with the surrounding oxygen. The study that is described in this paper enhanced our understanding....

on Blast Pressure analysis due to a partially confined explosion i experimental studies
International Journal of Protective Structures, 2011Co-Authors: Idan E Edri, V.r. Feldgun, Z Savir, Y S Karinski, D Z YankelevskyAbstract:This paper presents a first stage of a study aimed at understanding some characteristics of an interior explosion within a room with limited venting. An interior explosion may occur accidentally in ammunition storage, or due to a terrorist action, or as a result of a warhead explosion that follows its penetration into a closed space. The full scale experimental study is focusing on a single room sized space with rigid boundaries, at the center of which a TNT charge is detonated. The room has a limited size opening for venting at the ceiling. The effect of the charge size on the Blast Pressures has been investigated and a new insight with regard to the Pressure distribution on the walls as well as the Pressure attenuation depending on these parameters has been gained.

improving the safety of transportation of dangerous goods an experimental study
Transportation Research Record, 2009Co-Authors: M. M. Elshafey, Ettore Contestabile, A Abd El O Halim, O. B. IsgorAbstract:The transportation of dangerous goods (DG) represents an important portion of the overall freight transport worldwide. Ground transport (excluding pipelines) moves approximately 21% to 31% of the total tonnage of DG in Canada. Accidents involving DG might occur at any time at any location along transport routes or within storage areas, and not only do they have an effect on people and the environment, but also they can have a great effect on the national economy. This paper presents the details of an experimental investigation studying the Blast attenuation capability of suppressive shield panels (SSPs). Suppressive shield technology can be used for the storage, processing, and transport of explosive materials and can also be applied to protecting attractive targets and infrastructure deemed vulnerable to explosive attacks. Various configurations of commercially available steel angles were assembled as SSPs and evaluated for their ability to attenuate Blast Pressure from detonating Pentolite charges. Resu...

Blast loading response of reinforced concrete panels reinforced with externally bonded GFRP laminates
Composites Part B: Engineering, 2007Co-Authors: A. Ghani Razaqpur, Ahmed Tolba, Ettore ContestabileAbstract:The behavior of reinforced concrete panels, or slabs, retrofitted with glass fiber reinforced polymer (GFRP) composite, and subjected to Blast load is investigated. Eight 1000 × 1000 × 70 mm panels were made of 40 MPa concrete and reinforced with top and bottom steel meshes. Five of the panels were used as control while the remaining four were retrofitted with adhesively bonded 500 mm wide GFRP laminate strips on both faces, one in each direction parallel to the panel edges. The panels were subjected to Blast loads generated by the detonation of either 22.4 kg or 33.4 kg ANFO explosive charge located at a 3-m standoff. Blast wave characteristics, including incident and reflected Pressures and impulses, as well as panel central deflection and strain in steel and on concrete/FRP surfaces were measured. The post-Blast damage and mode of failure of each panel was observed, and those panels that were not completely damaged by the Blast were subsequently statically tested to find their residual strength. It was determined that overall the GFRP retrofitted panels performed better than the companion control panels while one retrofitted panel experienced severe damage and could not be tested statically after the Blast. The latter finding is consistent with previous reports which have shown that at relatively close range the Blast Pressure due to nominally similar charges and standoff distance can vary significantly, thus producing different levels of damage. © 2006 Elsevier Ltd.

Blast Pressure Distribution on a Buried Obstacle in a Porous Wet Soil
International Journal of Protective Structures, 2011Co-Authors: V.r. Feldgun, Yuri S. Karinski, David Z. YankelevskyAbstract:The paper presents a comprehensive approach to simulate the Blast Pressure distribution on a rigid or flexible planar or curved obstacle buried in a porous soil medium. The Lyakhov three-phase model is adopted to take into account the volumetric components of the soil medium (air, water, and solid matrix) and their properties, in the formulation of all the branches of the equation of state that simulates the soil. The present approach considers both the bulk and the shear elastic-plastic behavior, including the effect of soil Pressure on the yield strength for the stress tensor deviator. Both Godunov and the variational-difference methods are applied to solve the problem of Blast wave propagation within the soil medium. An example problem of an explosion in a porous medium is presented, and the analysis of the soil-obstacle interaction under the Blast action using the proposed method shows good correspondence with available experimental results. The Pressure distribution along the envelope of a rigid obst...
