Structural and temporal features of high-rate deformation of metals.

Dynamic yield stress values predicted within the structural-temporal approach based on the incubation time concept and those found from the empirical Johnson-Cook formula and its known modification are compared with the examples of steel, nickel, and an aluminum alloy subjected to high-rate plastic deformation. It is shown that the structural-temporal approach is an efficient and convenient tool for calculations in a much wider range of deformation rates. [ABSTRACT FROM AUTHOR]
