In the uniaxial compression, deformation with damage and temperature-rise of two types of plastic-bonded explosives were recorded by means of a high-speed camera and a high-speed infrared radio camera. The results show that the damage evolution and the temperature-rise of the two PBXs are obviously different. As for the PBX with a low content of the binder, the brittleness of the material is characteristically obvious, the strain softening of the stress-strain curve is accompanied with a damage evolution, and the crack formation is due to the failure of the sample, where there existed a local temperature band. As for the PBX with a high content of the binder, the toughness of the material is observed, the strain softening in the stress-strain curve is absent, and the damage is distributed evenly, with a network temperature-rise in the direction of shear.
