| Abstract: | In view of the mechanical characteristics of the porous hardand brittle materials the existing problems in the measurement of thedynamic mechanical behavior based on the conventional SHPBexperimental technique were analyzed on the basis of the two fundamentalassumptions in the SHPB experiment. The influencies on experimental results ofsome factors such as the incident bar, transmissionbar, sensors, specimen, incident wave shape and the data processingalgorithm were investigated, respectively. According to theresults, a modified experimental technique was developed for measuring thecompressive stress-strain response of these materials. This paperprovides some gaidances the design of SHPB experiments for porous materials orbrittle materials. |
