Trajectory prediction and risk assessment of a flying debris generated by blast wave loading

为了评估由冲击波载荷产生的飞行碎片的风险，我们开发了一类数值模拟代码来预测它们的轨迹和撞击条件。我们的代码的二维版本已经成功地通过一系列激波管实验的结果进行了验证，在激波管实验中，使用高速摄像机可视化了固体物体的激波运动。模拟得到的轨迹和观测到的物体的角位移吻合得很好。

In order to assess the risk of flying debris generated by blast wave loading, we have developed a class of numerical simulation codes for predicting their trajectories and impact conditions. A two-dimensional version of our code has been successfully validated by the results from a series of shock tube experiments, in which the shock-induced motion of a solid object was visualized using a high-speed video camera. We have obtained the satisfactory agreement between the simulated and observed trajectories and angular displacement of the object.
