2013 SPH法によるShaped Chargeの数値シミュレーション : ジェット生成とターゲット侵徹(S04-2 FEM/メッシュフリー法/粒子法とその関連技術(2),S04 FEM/メッシュフリー法/粒子法とその関連技術)
詳細
The SPH solver of the AUTODYN-3D was applied to the numerical simulation of shaped charges. The hypervelocity particles of SPH precisely represented the profiles of shaped charges, including the jet velocity, the velocity gradient and the elastic-plastic phase changes of the liner material. Using the calculated jet particles, the target penetration process was simulated. The results of the calculation were time-consuming and some parameters did not conform with the traditional theory of the penetration.
