Numerical modeling and simulation of underwater explosions interacting with discrete rigid bodies
AIP Advances, 2023 The smoothed particle hydrodynamics (SPH) method is widely used to simulate underwater explosion phenomena. However, previous studies have focused on the interaction between the underwater explosion and continuous structures (e.g., steel plates and dams),

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 ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
