A high-strength explosive composition for the seismic columns containing expanded ammonium nitrate (AN) 67.3%, wood powder 1%, diesel oil 0.3%, wax 0.7%, TNT 25% and aluminum powder 5.7%, was developed by using high energy aluminum powder additive based on the common thermo-plastic expanded AN explosive composition, optimizing the formulations of inner explosive charges, and determining their explosion properties experimentally.
Simulation Test System With Gas Gun For Impact Ignition Of Explosive Charges
An experimental method is used to investigate the unconfined explosive charges for five explosives with three different finite dimensions. The'pte-explosion temperature rise',criti-cal temperature and distribution of temperature field are determined. The autocatalysis mecha-nism of explosive JH9105 and the supercritical characteristics of thermal explosion are discussed.
The explosive performances of DAAT were calculated theoretically by VLW equation-of-state (EOS) and the results showed that several explosive formulations based on DAAT have high-energy and insensitive performance.
Secondly, the effect of explosion shock waves, produced by plastic strip-like explosive, on welding residual stress distribution was predicted with coupled Lagrange-ALE algorithm.
Transformation characteristics of TiNi/TiNi alloys synthesized by explosive welding
The black shales also contain K-bentonites from explosive, felsic-intermediate volcanism, the distribution of which also supports orogeny to the southeast.
The model of a current meander is put forward, which explains the generation of an inductance electric field, current wedge, and other effects of the explosive onset of a substorm.
