PBX9501

10 outputs, 7 inputs, 7000 observations. This data consists of simulated rate stick experiments for PBX 9501, a commonly-studied high explosive (HE), with various jacket materials. Rate stick experiments, or cylinder tests, are carried out by detonating a cylindrical stick of HE surrounded by a metal jacket. Photon Doppler velocimetry (PDV) diagnostics are used to measure the liner velocity at various axial locations to track the progress of the detonation. These 2D experiments were simulated using LANL’s free Lagrangian hydrodynamics (FLAG) code (Crowley (2005), Burton (2007)). For 14 different jacket materials (with fixed EoS, strength, damage and melt models), a rate stick experiment is performed for PBX 9501 under 500 different settings of the 6-dimensional JWL equation of state (Lee, Hornig, and Kury (1968)). The response includes the velocity and displacement of the jacket linear, as measured by the 5 PDV probes, 8 microseconds after detonation.10个输出变量、7个输入变量，共7000条观测样本。 本数据集包含针对PBX 9501（一种被广泛研究的高爆炸药（High Explosive, HE））开展的、搭配不同套筒材料的模拟杆式速率实验。杆式速率实验（又称圆柱实验）的操作流程为：将包裹有金属套筒的高爆炸药圆柱药柱引爆，以此开展实验。实验采用光子多普勒测速仪（Photon Doppler Velocimetry, PDV）诊断技术，在不同轴向位置测量套筒内壁的速度，以追踪爆轰的发展进程。 本数据集的二维实验均通过LANL开源的拉格朗日流体动力学（Lagrangian Hydrodynamics, FLAG）程序进行模拟（Crowley, 2005；Burton, 2007）。针对14种不同套筒材料（其状态方程（Equation of State, EoS）、强度模型、损伤模型与熔化模型均固定），研究人员针对PBX 9501开展了杆式速率实验，实验中采用了6维JWL状态方程（Lee, Hornig & Kury, 1968）的500种不同参数配置。实验响应结果包含爆轰发生8微秒后，由5个PDV探针测得的套筒内壁速度与位移数据。
