THE INFLUENCE OF THE STRONG DYNAMIC DEFORMATION ON THE STRENGTH PROPERTIES OF METAL SANDALLOYS UNDER SPALLFRACTURE
The influence of shock compression intensity on the spall strength of copper, brass, nickel,Armco-iron, stainless steel and Nickel-titaniumalloy in the pressure range of 10-80 GPa is investigated by registration and subsequent analysis of the full wave profiles. It is found that the strength of metals subjected to strong twinning under the shock loading is increasing with the pressure in shock wave and have the threshold character due to the thermal weakening undermaximumamplitudes of the shock wave. The metals with the phase transitions have more complicated character of strength dependencies on shock compression intensity.
