Noncrystallographic structural deformation levels in strongly excited systems

Conclusion Therefore, the analysis performed in the previous sections on the experimental data and results of modelling by the molecular dynamics method permits making a deduction on the possibility of the formation of strongly excited systems of noncrystallographic structural deformation levels during loading. As an experimental investigation showed, for all the kinds of static loading utilized their origination is associated with the pre-fracture stages. Crack propagation over the noncrystallographic interfacial boundaries of the fragments indicates this. Under shockwave loading the macroflux motion with the grains is also a new, larger-scale dynamic deformation level (compared with the dislocation level).Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 2, pp. 107–120, February, 1990.
