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.
In this paper a valuable method for sealing wax at the both ends of small explosive Charges was presented, and relative problems such as nozzle improvement, spray temporature, flow of wax liquid, Choice of filter system and theoretical design were described.
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.
