Since liquid hydrogen has some complex physical behaviors in a relatively wide range of pressure and temperature, one more accurate and appropriate ab-initio simulation method is urgently required.We used the Coupled Electron-Ion Monte Carlo (CEIMC) method to simulate the single shock compression ex...

Based on the Viscose-Statistical Crack Mechanics (Visco-SCRAM) model describing the dynamic response of PBXs', a modified model is obtained through changing the value scope of the direction vector of crack surface, the value of initial flaw size and the volumetric constitutive relation.Then the new ...

Numerical simulations are carried out to design the Pillow flyer of Ti-Cu-W system, and the impact loading and quasi-isentropic loading of the bismuth sample are also carried out.We experimentally investigate the intricate physical process of impact melting and resolidification.Experiment results of...

In order to investigate the damage effect of aluminized explosives in concrete, three types of aluminized explosive with different aluminum contents were blasted on small concrete targets.High speed camera was used to capture the blasting progress.Experimental results show that the depth of charge h...

Based on three-dimensional Euler equation and elementary reaction model of hydrogen/oxygen system which includes 8 species and 48 elementary reactions, the rotating detonation in the annular combustor was simulated numerically.The basic three-dimensional structure of the rotating detonation consists...

High-pressure and high-temperature Brillouin scattering studies have been performed on molecular liquids, including water (H₂O), ammonia (NH₃), ammonia dihydrate (NH₃·2H₂O) and methane (CH₄) by using a diamond anvil cell (DAC).The acoustic velocity and adiabatic bulk modulus have been determined fro...

The magnetically driven quasi-isentropic compression loading technique (ICE) is used to investigate the mechanical behavior of fluorine rubble F₂₃₁₁ which is often used in energetic composites.By means of laser displacement interferometer, particle velocities of the interface between F₂₃₁₁ and windo...

The equation of state of detonation products for RDX explosive at different initial densities is calculated by adopting the program based on the statistical physics model.It is found that only gas phase product generates after the explosive detonation when the initial density of explosive is less th...

The effect of residual stress of big tilling depth rotary blade with 350 mm turning radius for laser shock peening (LSP) was researched, and the theoretical stress of rotary blade were analyzed by ANSYS.The stress concentration region was at the outer corner of tool shank.The LSP process was also si...

Negative thermal expansion (NTE) ZrW₂O₈ powders were prepared by solid-state reaction with ZrO₂ and WO₃ powders.In situ high-pressure X-ray diffraction measurements for powder ZrW₂O₈ were performed by using a diamond anvil cell (DAC) with synchrotron radiation facility.The result shows that powder Z...

The elastic-plastic hydrodynamic L-R two-step Euler method was used for studying metal flyers colliding behaviors driven by cylinder explosion.The simulation results just accorded with the radio graphs when the flyer metal was lead, and the melting and spall phenomenons were described by simulation....

The sequence of events during the impact of tandem warhead system was divided based on the damage model of tandem warhead system to concrete target.Combined with the pre damage of front shaped charge to concrete target, the influence of concrete target with pre-drilled cavities on the penetration pe...

A hole polaron in the Emeraldine-base polymer under pressure was investigated on the basis of an extended Ginder-Epstein model.We found:the polaron relaxasion was weakened to disappear and the original local charge tended to distribute on the whole chain; Because of the pressure' excitation energy g...
