Planar shock compression experiments are performed on a Zr-based bulk metallic glass(BMG),Zr_(51)Ti_5Ni_(10)Cu_(25)Al_9 at peak shock stresses from 10 GPa to 27 GPa to investigate its plastic behavior under high pressure and high strain-rate.The particle velocity profiles measured at the free surface of the samples are analyzed to estimate longitudinal stresses of the Zr-based BMG in the shock loading process,and then shear stresses are obtained by comparing longitudinal stresses with a hydrostat.Though the...
