In this paper, we carried out experimental studies on the influence of the strength of materials on the pressure calibration under non-hydrostatic compression using the diamond anvil cell and synchrotron radiation X-ray diffraction technology.Pt and Au were used as the pressure marker in the same hi...

Out-of-plane dynamic crushing response of self-similar second order hierarchical square honeycombs under impact loading was simulated using ABAQUS in the present study to investigate the influence of the aperture size, the yield stress of parent material and the impact velocity on the crushing model...

Using a material testing machine and the split Hopkinson pressure bar (SHPB) system, we investigated the quasi-static and dynamic compressive behaviors of porous titanium with regular pores, and studied the effects of the strain rate and porosity on the Young's modulus, yield strength and energy abs...

In order to set up a three dimensional damage model for composite laminates with a circular hole, based on the failure criteria proposed by Linde et al., we at first implemented the user-defined material subroutine UMAT in the finite element code ABAQUS using the factors of fiber and matrix to chara...

The explosively driven fragmentation of ductile metals is a complex phenomenon, for that the fracture modes and mechanisms are affected by materials, configuration and explosive energy in different ways.In this research, we investigated experimentally the deformation and fracture behavior of the exp...

In the present study we studied the influence of the mass of ferrocene precursors on the synthesis of carbon nanotubes with methane and oxygen as the explosive sources.The morphology and structure of the carbon nanotubes were characterized using X-ray diffraction, transmission electron microscopy an...

Based on the first-principles and using the double cluster with full single and double excitations plus perturbative treatment of triples (CCSD(T)) and the aug-cc-pVQZ basis set, many-body contributions to the cohesive energy, the zero-point vibration energy and the equation of state of solid argon ...

In order to study the influence of detonation reaction on the morphology and phase of multi-walled carbon nanotubes (MWCNTs), the mixed explosives, made from MWCNTs and RDX with a given mass ratio, were detonated in the reaction kettle.The samples before and after detonation were characterized using...

In this work we modified the 1D implosion and the MHD code—MC11D by introducing the equation of state (EOS) in analytical form into the program.Then, using the modified code, we simulated a cylindrical implosion magnetic flux compression experiment on the copper sample and obtained the velocity hist...

In this research, we proposed a method for deblurring of images captured in the dynamic deformation of materials.By this method, deblurring was achieved based on a dynamic-based approach, which was used to estimate the point spread function (PSF) during the camera exposure window.The deconvolution p...

To investigate the influence of the charge structure on the cook-off characteristics of the solid rocket motor, we established 3 simplified cook-off models with 3 different charge structures, including the composite, the mono tube and the star tube, for the solid rocket motor with HTPE propellant.We...

To investigate the fluid-structure interaction of the one-dimensional strong shock wave with the plate, we took the compressibility of fluid and structural material into account and, by introducing state of equation of water and structural material into our theoretical analysis, obtained the reflect...

In this research, to investigate the pressure distribution of the shaped charge explosive in the underwater near-field, we conducted both experimental studies and numerical simulation and, by comparing the results from the simulation with those from the experiments, validated both the numerical mode...

The relationship between the structural parameters and penetration capacity of annular shaped charge is hard to express by analytical mathematical formulas, so it is meaningful to establish a model to describe this relationship using the grey relational analysis theory.In our study, the orthogonal t...

To appraise the technical feasibility of welding thin-walled projectile for penetrating multi-layered reinforced concrete targets, we used the finite element method to simulate the penetration process and designed a set of comparative tests based on the simulation results.The welded thin-walled proj...

To find out whether there exists an increased shock wave velocity when the Ti-Si reactive powder is loaded by shock, we used the gas gun to drive the flyer to impact the active Ti-Si powder and initiate its reaction.In the process of the powder's self-propagating reaction experiment, high speed came...

In order to improve the formation and penetration performance of multi-explosively formed projectiles (MEFP), we analyzed the influence of the charge cover (both its shape and wall thickness), the shell thickness, the explosive initiation modes as well as the fragments bracket on the projectiles for...

In the present work, to investigate the effects of high pressure processing (HPP) treatment on the quality and structure of the perch (Lateolabrax japonicas) fillets during cold storage, we treated samples with different HPP conditions (200, 250 and 300MPa for 9min) and then stored them at 4℃ respec...

The bend structure is one of the most basic building elements of a coal tunnel.A good understanding of its influence on the gas explosion is essential for estimating the tunnel's blast resistance and thus for optimizing the tunnel's design.In the present work, we studied the influence of the bend st...
