| Research Abstract |
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.
