Abstract
The paper is devoted to establishing of general regularities of dynamic destructions (those of dynamic failure and dispersion) in metals, under high intensity external action in the dynamic range of nonequilibrium states t ~ 10–6–10–9 s. Using a crystal lattice pair potential, there is determined an expression for compressibility (susceptibility) of a loaded sample that depends on failure centers density. Determining of common relaxation attributes for non-equilibrium systems allows prediction of unstudied systems’ behavior. Predicted is behavior of plutonium metal, thorium, uranium in the range of non-equilibrium states t ~ 10–6– 10–9 s, Е ~ 30–300 J/g using established temporal invariant of metals behavior under extreme conditions and experimental data on critical pressure, causing failure of plutonium metal.
