A relationship has been established between the level of compressive stress necessary for the commencement of simultaneous deformation of the dissimilar phases of a composite material on the one hand and, on the other, the magnitude of the jump in st

1. In the pressing of parts from powders in hydrostatic and isostatic pressure vessels the processes occurring in the material being densified are identical with those characterizing pressing in dies: An indispensible element of pressing is the destr

1. The density of a porous (powder) body being pressed is a function of the stress tensor, but is not uniquely related to the latter's greatest component. The intensity of the compact densification process depends directly on the relative magnitude o

The plasticity function of a composite material (like that of a porous powder medium) depends on the first invariant of the stress tensor, and the intensity of this dependence, assessed by the internal friction angle, is determined by the magnitude o

As in porous bodies, in dense composite materials plastic deformations may cause an increase in the local concentration (density) of elements of the “hard” phase in zones of active flow of the material. The intensity of structural rearrangement (

1. The limiting stressed state of powder materials is described by a linear function known as “Coulomb's flow criterion.” 2. It is demonstrated that, in stress-distribution determinations, powder materials may be analyzed from the viewpoint of th
