In this study, the anti-penetration performance of polyurea/ASTM1405-steel composite plate subjected to high velocity projectile was analyzed. Two kinds modified polyurea material (AMMT-053 and AMMT-055) were selected a ballistic impact testing system including speed measuring target high-speed camera designed. This experiment conducted with rifle 5.8 mm explore effects by coating thickness, position glass-fiber cloth on plate. The result showed that different between two types polyurea,...
According to the randomness of spatial distribution and shape internal cells closed-cell foam aluminum based on Voronoi algorithm, we use ABAQUS model random polyhedrons pore firstly. Then, algorithm generating with size wall thickness is written by Python Fortran, mesh polyhedral particles was established read in TrueGrid software. Finally, impo rted into LS-DYNA software remove polyhedron part cell. Compared results scanning electron microscopy antiknock test, morphology properties are...
Abstract In the present study, stress-strain relationship of 6063-T5 aluminum alloy over wide ranges temperatures and strain rates was investigated. Firstly, quasi-static tensile tests high temperature split Hopkinson pressure bar (SHPB) were carried out for alloy. tests, experimental ranged from room to 350℃, dynamic rate 500/s-6000/s. Secondly, effects on mechanical properties materials discussed. The results showed that had obvious softening effect hardening effect, but may also occur...
In this paper, LS-dyna software was used to simulate the charging process of cylindrical shell when EFP has different angles, and some interesting phenomena laws were found. Cylindrical elastic wave σr generated impacted by EFP. The correlated with time required for charge be successfully detonated. When warhead penetration Angle θ ranges from 0° 10°, increases linearly (cosθ)-1/2. With increase θ, tangential velocity vy had an obvious effect on impact shell, linear relationship between...
Residual stresses can be generated in aluminum alloy thick plates used widely as the blank of aeronautical thin-walled monolithic components because non-homogeneity plastic deformation induced manufacturing process. The release residual stress high-speed milling process causes machining component which severely influence its quality. Therefore, finite element simulation method is established for workpiece deformation-released blank. values, well calculation values obtained by deflection...
