High energy explosive was used to create a powerful and planar shock wave for accelerating flyer plate to high velocity, and high pressure was produced when flyer impacting with the sample. in the experiments, the impactor was brass and target was ofhc copper. by measuring the shock wave velocities of hr2 steel, high - density glass, aluminium alloy ( ly12 / lf6 ), magnesium - aluminium alloy ( mb2 ), polymethyl methacrylate and air, shock pressure and release isentrope of ofhc copper have been obtained
採用化爆加載、平面波發生器和空腔增壓技術,以黃銅為飛片,無氧銅為靶板,測量了抗氫鋼( hr2 ) 、重玻璃( sio _ 2 ) 、
鋁合金( ly12 lf6 ) 、
鎂鋁合金( mb2 ) 、有機玻璃( pmma ) 、空氣( air )和無氧銅( ofhccopper )各阻抗匹配樣品中的沖擊波速度,上述材料的hugoniot狀態參數c _ 0 、均為已知,由此確定了無氧銅的沖擊加載壓力和等熵卸載后的狀態,得到了等熵卸載路徑。
