Third Progress Report on Plastic Deformation of Steel Under High Pressure

Abstract

Tests of the mechanical properties of steels under high hydrostatic pressure which were described in previous reports were continued, using four samples of armor plate of varying ballistic qualities. The conclusion, in accord with the results of other lines of investigation, is that ballistic behavior is closely associated with fairly obvious characteristics- such as inhomogeneity, brittleness, and so forth- which can be investigated by standard methods. The conclusions regarding strain hardening and conditions for fracture, given in the earlier reports, have been improved, but not essentially changed, by considering the true stress state in the neck of a tensile specimen.
