The incident wave and transmission wave varying with the time have been obtained by SHPB experiment.The relationship curve for sress and strain of material copper has also been obtained . The dissipation of energy in the material is also obtained ,It indicates that the are littile energy dissipated in materia copper because of little pore space in the metal. The whole process has been numerical simulated by LSDYNA970 procedure. The results between the experiment and numerical simulation are accordance. It is a new path to investigate the dynamic mechanigal property of materials. The results of measure and numerical simulation indicate that the semiconductor strain gauges can be used to get the vivid signals of the weak transmission strain-pulse.
