【 摘 要 】

In this paper the shock response of CrS, a cermet of potential interest as a matrix material for ballistic applications, has been investigated. Compacts with a Chromium: Sulfur ratio of 1.15:1 were investigated via the plate-impact technique. These experiments allowed the material to be loaded under a one-dimensional state of strain. Embedded manganin stress gauges were employed to monitor the temporal evolution of longitudinal and lateral components of stress. Comparison of these two components has allowed assessment of the variation of material shear strength both with impact pressure/strain-rate and time.
