Method of determining the rheological and energy characteristics of the shock compression of metals

A method for determining the shear stress relaxation time and the heat release due to deformation of a material is developed based on the Kolsky technique using a split Hopkinson bar. The method was tested in experimental studies of the rheological and energy characteristics of AMg5 M aluminum alloy in the range of strain rates from 300 to 1500 s$^{-1}$. The relationship between the relaxation time and the thermal and internal energies of AMg5 M alloy during its shock compression was determined.
