Uninstrumented Measurement Method for Granular Porous Media Blast Mitigation Assessment

Abstract

The current paper is concerned with testing the efficiency of a uninstrumented method in assessing granular porous media capacity to mitigate blast impulse. A thin plate constant deformation test was carried out based on the findings obtained throughout blast-structure interaction phenomena. The proposed test requires only post-test measured data and no test instrumentation is needed. The test protocol under scrutiny consists of a short series of 200 g TNT charge detonations at 1000 mm distance from the tested structures. All test results have shown impulse mitigation. The findings obtained in the test under scrutiny tally those in the pendulum test. The final section of the current article is concerned with the improvement and shortcomings of the test developed.

Numerical and Experimental Study of the Use of Mineral Pumice in the Core of the Sandwich Panel to Absorb the Shock Wave

“…Mahmoud et al [8] investigated explosive loading on reinforced concrete slabs with aluminum foam boards. Rotariu et al [9] investigated the measurement of pulse attenuation in environments of porous granular materials by experimental test method. They estimate the amount of wave attenuation using a square steel sheet behind a pack of granular materials by measuring the permanent change in angle of the sheet.…”

Experimental Study on the Dynamic Response of Polyurethane/fly Ash Ceramic Foam

“…In the last decades almost all the proposed blast attenuation solutions included the use of energyabsorbing or energy-dissipating materials. Thereby, the scientific studies related with this particular topic were focused on identifying effective mechanisms for blast energy dissipation and impulse attenuation [1][2][3][4].…”
