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

为了评估爆炸波载荷产生的碎片飞出的风险，我们开发了一类用于预测其轨迹和撞击条件的数值模拟程序。一系列激波管实验的结果已经成功地验证了我们的程序的二维版本，在这些实验中，使用高速摄像机可视化了固体物体的激波诱导运动。我们得到了令人满意的一致的模拟和观测的轨迹和角位移的对象。

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.
