No.548 地中に埋設された爆薬の爆発挙動シミュレーション(埋設深さ DOB = 8.0 m)

地中に埋設されたTNT爆薬250kgの爆発挙動を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。爆薬の埋設深さを8.0mとしたケース(B.O.D = 8.0 m)の結果を示します。

No.548 Simulation of underground explosion behavior with different buried depth of explosive (Depth of Burial,DOB = 8.0 m)

We will show you examples of a simulation for underground explosion behavior caused by 250 kg TNT explosives buried underground. The Structured ALE Solver (S-ALE) are used. Here is the results for which the explosive is buried at a depth of 8.0m from the ground surface (D.O.B = 8.0 m).

Keywords: Structured ALE, 3D, 1/4 model, buried explosion, TNT 250kg, H.E shape = cubic, depth of burial = 8.0m

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