| Abstract: | Strong shockwave experiment was performed in this work and the pressure of sapphire is 42GPa.After the experiment,the shocked sample was recovered.Through the SEM,obvious melted trace upon the sample was observed;the experiment confirms adiabatic shear banding is the primary mode of failure in the strong shock-loaded sapphire. |
