Damage response of steel plate to underwater explosion: Effect of shaped charge liner
TL;DR: In this paper, a Smooth Particle Hydrodynamic (SPH) method based on mesh-free Lagrange formulation is applied to simulate an entire process of a shaped-charge detonation, formation of a metal jet as well as penetration on a steel plate.
Journal ArticleDOI
Underwater explosion of cylindrical charge near plates: Analysis of pressure characteristics and cavitation effects
TL;DR: In this article, a coupled scheme utilizing advantages of the Runge-Kutta discontinuous Galerkin (RKDG) method and finite elements is applied to investigate cavitation induced by rarefaction waves during a near-field underwater explosion of cylindrical charge.
Journal ArticleDOI
SPH-FEM simulation of shaped-charge jet penetration into double hull: a comparison study for steel and SPS
TL;DR: In this paper, a hybrid algorithm fully utilizing advantages of both SPH and FEM is proposed to simulate a metal-jet penetration into a double hull made of different materials, namely steel and SPS (Sandwich Plate System).
Journal ArticleDOI
Pressure characteristics of bubble collapse near a rigid wall in compressible fluid
TL;DR: In this paper, a hybrid algorithm was adopted to simulate bubble motion and associated pressures near a wall combining Level Set-Modified Ghost Fluid Discontinuous Galerkin (LS-MGF-DG) method and boundary element method (BEM).

TL;DR: In this paper, a mesh-free methodology, smoothed particle hydrodynamics (SPH), is presented for a shaped charge penetrating underwater structures, and the results obtained for different cases - for various materials of explosives and liners - are discussed and compared, and as a result more suitable parameters of the shaped charge in order to increase the penetration depth are obtained.
