No.552 Simulation of Shock Wave Propagation Behavior in Underwater Explosion(DOC=30cm)

This is an example of simulation for the behavior of the initial shock wave propagation when 10g of TNT explosive charge explodes underwater. The Structured ALE Solver (S-ALE) are used. Here is a case where the explosive charge was located at a depth of 30 cm below the water surface.

Keywords: Shockwave propagation due to UNDEX (underwater explosion), Structured ALE, 3D, 1/2 model, TNT 10g, H.E shape = cubic, Depth of Charge = 30cm

Tools: LS-PrePost ver.4.9, LS-DYNA MPP Win64 R13.1.0
