Prediction of reduction of blast load pressure by granular medium layer
Journal Title: Bulletin of the Military University of Technology - Year 2016, Vol 65, Issue 3
Abstract
The paper presents numerical analysis of effectiveness of reduction of blast load pressure acting on the ceiling by using granular medium with a cover plate. The analysis was conducted using the discrete element method. The variability of stress acting on the ceiling under blast load impulse is presented. It is shown that plate weight significantly influences on the character of ceiling pressure distribution. The obtained numerical results reveal multiple stress wave reflection effects in granular medium placed between the rigid cover plate and the ceiling.[b]Keywords[/b]: granular medium, blast load, discrete element method
