Algorithm describing pressure distribution of non-contact TNT explosion [PDF]
Biuletyn Wojskowej Akademii Technicznej, 2014 [b]Abstract[/b]. The aim of this study is to develop a computational algorithm, describing the shock wave pressure distribution in the space induced by non-contact TNT explosion. The procedure describes pressure distribution on a damp surface of the hull.

Resistance of GPS samples to non-contact underwater explosion
Journal of Physics: Conference Series, 2017 Test data obtained from experiments on GRP test samples in the explosion chamber of Krylov State Research Centre are given. Characteristic features of material damage accumulation and failure processes are discussed based on the experimental data. The sample material damage is assessed versus three indicative effects (criteria): binder failure, fiber ...
