Conclusions

  1. 1.

    As a result of an experimental investigation, the relation was established between the tangential and normal stresses on shear faces.

  2. 2.

    In the first stage of compaction, the coefficient of lateral pressure depends only on interparticle friction; with rise in pressure, it increases, the increase being the more rapid the lower the mechanical strength of the powder particles.
