Abstract

There are established the boundaries of conserving functional properties of metals at dynamic failure under extreme conditions (longevity range t ∼10⁻⁶÷10⁻¹⁰s). The methods of non-linear physics made it possible to determine universal attributes of non-equilibrium systems evolution conditioned by collective effects and phenomena of self-organization in the appearing dissipative structures. In the paper there is presented a universal failure surface that allows simulation of metals behavior under laboratory conditions and forecast of time boundary of functional properties conservation.
