Abstract

Abstract

By means of high-speed camera and VISAR interferometer, the expanding characteristics of HR-2 steel tube have been investigated under two head-on colliding detonation waves. The images of tube expanding process were obtained successfully by high-speed camera, and the radial displacement data and radial velocity curve of specific position in HR-2 steel tube were obtained too. In addition, we used LSDYNA-3D program to simulate the progress of the steel tube expansion, the results were coincident with the experimental results.
