Abstract
Results are presented from an experimental study of the effect of heating on the cleavage fracture of four explosive compounds based on hexogen and octogen. The loads that are critical in terms of collision velocity and pressure in the compressive loading pulse are determined. Macroscopic cleavage fracture of the specimens occurs above these loads. It is shown that the type and percentage content of the binder influence the paths of the temperature dependences of these loads.
