Mechanical behavior of sand under high pressure and high strain rate

Characterizing of the mechanical behavior of sand under impact loading is necessary to estimate the power of explosive mines. Using Hopkinson pressure bars for its characterization only low and limited pressures can be applied. Therefore the experiments were performed on a high energy drop weight ma...
