Abstract：The geometric deformation at the early rear surface of thick target under impact loading was studied through numerical simulation, It was found that there exists a turnover time window during the thick target deformation. During the window period, the deformation is changed from former convex shape to concave shape, which is different from that of traditional thin target. Based on these results, we present an explaination on the experimental results by electric probe array technique. The window is very sensitive, and the electric probe array is closely related to the distance from the rear surface of the target, and therefore, the engineering experiment repeatability is not strong.
