Abstract

Abstract

In the present work, we developed a novel method combining the forward Lagrange method and the transfer function method to process the data of ramp wave compression experiments. Compared with traditional methods, this method is more suitable to process the data containing materials' complex behaviors and produces more accurate results. Meanwhile, this method has lower precision requirement regarding the initial gauss of testing material parameters. The feasibility and robustness of the transfer function method was analyzed, and the application of the forward Lagrange method and the transfer function method were examined in forward data processing of strength measurement experiments under ramp wave compression.
