| Abstract: | An experiment technique is presented which is availiable to study dynamic properties of energetic materials under impact loading by means of materials testing system. In order to raise the loading rate, the dependence of the frequency of square wave is studied. The function that MTS is used in high strain rate experiment was developed. The results show that the strain rate for energetic materials is as high as 4/s. The loading rate is not dependent on the frequency of square wave. |
