Cylindric and spherical steel projectiles were launched by using a twostage light gas gun at LSD to impact onto an explosive charge (TNT/RDX=40/60)with a steel cover plate. Critical projectile velocity to initiate the detonation in the charge is obtained for various projectile attacking angles and different cover plate thicknesses.
The method combining numerical simulation with analytical solution of strong explosion was employed to determine blast load on the inner wall of an explosive chamber produced by a concentrated charge with different weight.
Based on the analysis of the press ure profile of the detonation products flow,an analytic solution is derived to c alculate the motion of an incompressible rigid-visco-plastic cylinder driven b y the divergent or convergent detonation of an explosive.
Using ALE algorithm and the JWL state equation for the product of explosive detonation,the numerical simulation of which the shock wave flows around an obstacle was conducted. The initial development of explosive field and the circle-flow behavior with an obstacle around an explosive source were obtained and the law of shock wave around-flow was analyzed.
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.

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.
The effect of the thermophysical parameters of a cooling medium on the macrokinetics of secondary physicochemical processes that occur in a hermetic chamber after the explosion of a solid explosive charge is studied.
