Description
Summary:The anti-vehicular landmine threat has increased greatly since 2005. It has now become one of theimportant causes of vehicle losses in combat operations, and a major threat to vehicle occupants in manycountries. Experimental and numerical studies of buried charge effects on structure and the measurement ofthe loading produced by landmines become important topics to study. These types of researches are done tosupport the development of improved vehicle protection to resist blast from landmines and ImprovisedExplosive Devices (IED's). Since it is a very challenging task to model explosive detonation, shock waveformation and propagation as well as interaction with structures from first principles, a phenomenologicalapproach was investigated. Many non-impulsive pressure models were investigated to model the damage ona plate from a blast landmine. The assumption that the loading generated by the blast is purely impulse iscritically investigated and rejected. A new non-impulsive time-distribution pressure model is then proposed.The outputs of the new pressure model were validated using experimental data from 6 kg TNT experimentaltests on plate flat.
