The vulnerability of the masonry envelop under blast loading is considered critical due to the risk of loss of lives. The dynamic behaviour of masonry infill walls subjected to dynamic out-of-plane loading was experimentally investigated in this work. Using confined underwater blast wave generators (WBWG), applying the extremely high rate conversion of the explosive detonation energy into the k...

This investigation compared four conventional vehicle armour materials for performance under blast loading. The parameters measured were resistance to deformation, mechanical toughness and metallurgical microstructure. It was found that two of these, the M steel and A steel, showed the least deformation and M steel showed better shock energy absorption. B steel had high toughness but showed sig...

purpose: since explosive blasts continue to cause casualties in both civil and military environments, there is a need for an understanding of the mechanisms of blast trauma at the human organ level, plus a more detailed predictive methodology. the primary goal of this research was to develop a finite element model capable of predicting primary blast injury to the lung so as to assist in the dev...

Several relations are presented in order to specify blasting dynamic loading associated with analytical, field and experimental analysis. Dynamic loading type, maximum pressure and consequent duration time can affect the numerical simulation results of fragmentations, damage zone and maximum radial crack length in the vicinity of the blast hole and ground vibrations. These in turn depend on the...

The effects of pre-pressurization on blast-loaded reinforced rectangular aluminum plates were studied experimentally. In this study, small (0.508 x 0.609 x 0.0016 meter) clamped plates with rivet attached reinforcing members were used as a basic model of the fuselage skin of a commercial aircraft. Both un-pressurized and pre-pressurized plates (static pressure of 41.4 kPa (6.0 psi)) were consid...
