Abstract

Abstract

The dynamic properties of special metallic cellular materials are tested difficultly by using the traditional SHPB techniques. In order to experimentally determine the initial dynamic collapse strength, plateau stress and to investigate the strain-rate effect, based on the current SHPB equipment, the transfer function of the system was proposed by using the deconvolution technique in inverse analysis with computer simulation. The improved data processing system of the SHPB experiment provides an effective approach for experimental study on the dynamic properties of foam materials.
