Abstract:

Split Hopkinson Pressure Bar (SHPB) was used to investigate the intrinsic anti-acceleration capability and mechanicalmodel of Lead Azide(LA), Lead Styphnate(LTNR), Tetraammine bis (5-nitrotetrazolato) Cobalt(Ⅲ) Perchlorate (BNCP). Results show that, the intrinsic anti-overload capabilities of LA, BNCP and LTNR are 5000 g, 5000 g, 10000 g respectively. Primary explosive charge suffered a short elasticity deformation, and then the brittle fracture occured.

Key words:military chemistry and pyrotechnics, primary explosive, high acceleration over loading, split Hopkinson pressure bar, mechanical model
