Abstract

Experimental results allowed the explanation of the nature of GMS as the mechanism of fragmentation under intense loads.The problem of fragmentation in its fundamental and applied significance covers a wide class of physical phenomena and scales. The fundamental aspects of fragmentation are related to the multiscale problems of field theory, the symmetry properties, statistical and energy laws of the behavior of out-of-equilibrium “critical systems”. Important features of “critical behavior” is manifested in the statistical patterns of fragmentation depending on the state, the initial structure of material, the load intensity, when “narrow” (exponential), “wide” (power-law) statistical distributions, as well as combinations of the latter are found. The qualitative changes in energy transformation laws, the fragmentation statistics are considered as the illustration of the Gaped Momentum States (GMS) scenario.
