    Abstract
  • Compressive behaviors of a polymer bonded explosive (PBX) and pressed Comp.B have been tested by means of a hydraulic material test machine at different strain-rates. Stress-strain curves of the materials at different strain rates have been obtained in this paper. According to the study on the mechanical behaviors of the two kinds of explosives at different strain-rates, the constitutive relations have been derived, which agree well with the experimental data from quasi-static tests during the linear elastic and strain-hardening stages of the stress-strain curves.
