Deformation, Fracture and Explosive Properties of Reactive Materials
Abstract
A range of techniques have been developed for studies of the behavior of explosives when impacted and for recording their strength, failure and ignition properties; these are described in Section 2. They include a drop- weight facility with transparent anvil, an instrumented drop-weight machine, a miniaturised Hopkins bar system for high rate of strain property measurement, laser speckle for studies of deformation and fracture of PBX's, an automated system for analysing speckle and moire' records, and a heat sensitive film technique for recording the position and temperatures of hot spots . The report gives data on the behavior of polymer layers, binder materials, a range of PBX's, a range of HMX's of different particle sizes, and PETN when impacted in the drop-weight test. Keywords: Explosives, Ignition, Impact, Sensitiveness, Hot spots, High speed photography, Deformation, Fracture, PETN, HMX, PBX.
