No.554 水中爆発における衝撃波伝播挙動のシミュレーション(DOC=100cm)

TNT爆薬10gが水中で爆発した際に発生する初期衝撃波の伝播挙動をStructured ALE Solver (S-ALE)を使用してシミュレーションを行った例を示します。爆薬が水深100cmで爆発したケースの結果を示します。

Keywords: Shockwave propagation due to UNDEX (underwater explosion), Structured ALE, 3D, 1/2 model, TNT 10g, H.E shape = cubic, Depth of detpth = 100cm (surface explosion)

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