This paper is concerned with the compressive characteristics of PBX(Polymer Bonded eXplosive) simulant at various strain rates ranging from 0.0001/sec to 3150/sec. The compressive characteristics of PBX at various strain rates are important in the prediction of deformation modes of PBX in a warhead which undergoes severe impact loading. Inert PBX stimulant which has analogous material behaviors with PBX was utilized for material tests due to safety issues. Uniaxial compressive tests at quasi-static strain rates and intermediate strain rates were conducted with cylindrical specimen using a dynamic materials testing machine, INSTRON 8801. Uniaxial compressive tests at high strain rates ranging from 1200/sec to 3150/sec were conducted using a split Hopkinson pressure bar(SHPB). Deformation behaviors were investigated using captured images obtained from a high-speed camera. Strain rate-dependent strain hardening model has been constructed to describe the compressive characteristics of PBX simulant with the variation of the strain rate.
