Abstract
The paper presents results obtained by numerical simulation of brittle spall fracture of Armco-80 iron under conditions of high-velocity deformation in one-dimensional counter waves of expansion. The spall fracture
process is described by the two-stage kinetic model (NAG). The paper authors analyze peculiarities of kinetics of
the damage accumulation process in the destruction zone. For comparison with the calculated results, the
experimental information on motion velocity W(t) of the free boundary of a loaded Armco-80 sample was used.
