Based on Liberman's statistical self-consistent field INFERNO mode, we calculated the equation of sate (EOS) and the Hugoniot of gold (Au) in a wide range of temperatures and densities. The electronic part of the EOS for Au was obtained by solving the self-consistent field Dirac equation at each den...

We investigated the high pressure infiltration sintering of coarse grained cemented carbide with low cobalt content, where WC-16%Co (mass fraction) substrate was used to provide cobalt. The initial WC powder was prepared with vacuum hydrogen reduction in order to isolate the oxygen impurity. This pa...

Preparing carbon nanospheres by gaseous detonation using oxygen-benzene mixture as the reactants is a new method. The crystal composition, grain size and phase structure were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results indicate that the dimension ...

A method was established for modeling the electrical explosive process of the micro metal foil based on reasonable simplification and a 1D code was developed to simulate the electrical explosive process of the micro metal foil. The numerical results agree well with the experimental data. Compared wi...

Based on the Monte-Carlo method, the meso-structural model of plastic bonded explosives (PBX) was established considering the grain size and location in random distribution by the non-linear finite element method. The influence of the binder and the defect hole to ignition characteristics of PBX in ...

As a new type of protective armor used to meet the needs of military transport vehicles for protection against projectiles of small kinetic energy, the porous plate can achieve the purpose of light-weight armor protection while ensuring the protective requirement. There has been little research on a...

The finite element software, ABAQUS, has been used to establish the simulation models in order to study the performance of 2A12 aluminum alloy targets (with a thickness of 2 mm) impacted by projectiles (with different boundary conditions), and the data of the targets' residual velocities and ballist...

The 5083 aluminum alloy is widely used in engineering, and is inevitably subjected to a variety of different loadings, including strong dynamic loading such as impact and collision.Therefore it is necessary to study its mechanical properties under loading of a wide range of strain rates as well as i...

In the present study, we developed a two-stage 6-8 type multianvil high pressure apparatus, which is capable of pressurizing centimeter-scale samples above 15 GPa.We also designed and tested the heater cell for the apparatus.The relationship between the heating power and the cell temperature was cal...

Spacer shaped charge can effectively adjust the detonation wave to improve the jet penetration capability; asymmetric initiation may lead to eccentric jet deflection, speed reduction and other phenomena, which is called the eccentric initiation effect.In the actual production process, however, it is...

In this work the constraint function of concrete was regarded as the distribution load associated with the transverse load, and the yield response of projectiles under the compressive and bending load was studied using the free-free beam theory, with the main parameters of the impact of the asymmetr...

In the present work we performed the first principles calculations based on the density functional theory and investigated the P42/mnm-Pnnm phase transition and the mechanical properties of SnO₂.For the exchange-correction energy we employed the generalized gradient approximation (GGA) in the Perdew...

In this work we obtained an analytic model CIM2 for the flow field of the reaction zone of condensed explosives in early-stage shock initiation using the characteristic line, the simplified equation of state and the simplified relationship between the material impedance and the shock impedance.By ch...

The dynamic analysis software ANSYS/LS-DYNA was used in combination with smoothed particle hydrodynamics (SPH) method to simulate the boundary effect in explosive cladding.The two-dimensional simulation results reproduced the phenomenon of metal jet and boundary effect and were consistent with the p...
