The results of development and practical approval of the computational technique based
on numerical solving the problem of continuum mechanics in a three-dimensional formu-
lation are presented to substantiate the rational parameters of explosive compaction of
workpieces for antifriction parts made of powder metal composite materials based on
fluoroplastic. The formulation of the problem, the physical and mathematical model of
the behavior of used metal and powder composite materials and the results of the numer-
ical solving the process of explosive compaction of cylindrical workpieces of copper and
fluoroplastic powder mixture with different percentage of the compressed components
are given. It is shown that the developed technique can be used as a basis for substantiating
of the design parameters of schemes for explosive pressing workpieces of other metal fluor-
oplastic compositions, including, for example, iron, nickel, aluminum and bronze powders.
Keywords: explosive, compaction, powder, metal composite, physical and mathematical
model, numerical simulation
