A one-dimensional Lagrangian backward integeration method was used to analyze VISAR records of isentropic compression experiments. The pressure history at the window-sample interface calculated by the interface velocity history was proved to be successful. A contrast calculation shows that the backward method is as accurate as the forward method. Analysis of the Z575 experiments shows that the isentropic compression curves of Al 6061-T6 are in good agreement with that by Hall C A.
