Abstract In order to study the influence of different spherical fragments on penetration depth concrete targets, AUTODYN-2D software is used model and simulate with diameters, materials velocities. Through analysis data, it found that tungsten alloy will not continue increase at higher speeds (when v > 1400 m / s, begins decrease). The process fragment penetrating analyzed, relationship betw...

Abstract In order to study the ignition characteristic of PTFE-based reactive materials (RMs), Al/W/PTFE RMs with different W powder contents were prepared and split Hopkinson pressure bar (SHPB) test was carried out under loading conditions. The temperature rise three calculated theoretically. material model parameters formulations by using mixture equation state theory Johnson-cook model, imp...

Numerical investigation becomes a highly demanding tool for the best design in engineering. With one validated numerical result available, further is possible to conduct. Especially, expensive and limited access civilian conduct test like blast experiment. capability of Arbitrary Lagrange Euler (ALE) solver coupling approach between structure air AUTODYN, detail three-dimensional assessment RC ...

The bundle-series initiation is currently used as the method for simultaneously transmitting blast signals from a detonator to large number of shock tubes blasting using and its modes affect ability probability signal transmission. A numerical study influence on pressure impulse generated by detonators transmitted has been undertaken with ANSYS AUTODYN code validated through experimental result...

This article presents the experiments on ballistic effect of plates formed by stacked Twaron® fabrics between 10 and 16 layer numbers impregnated with epoxy resin vacuum infusion method results Autodyn-2D® simulations using an axisymmetric model. The impact resistance panels produced was determined according to NIJ-STD-0108.01 standard. All were tested against 9 mm FMJ bullets at average veloci...

Abstract In order to study the effect of near-ground explosion energetic materials (EMs) on shell a vertical incinerator, different heights EMs 90 g TNT incinerator with exhaust gas outlet diameters was numerically simulated in three dimensions using AUTODYN software. The simulation results showed that maximum von Mises equivalent stress (mis. stress) occurred at upper edge outlet. Furthermore,...

Abstract The fracture process of the metal cylindrical shell under action implosion is numerically simulated by AUTODYN finite element software for expansion cracks on surface cases loading. Numerical computations were used to determine effect law engineering factors such as energy density explosives, thickness, and material crack-related parameters. results show that radius along axial directi...

The need for assessing and retrofitting structures increased with time as terrorism-induced explosion trends rose time. This paper presents a numerical investigation on performance assessment of two-story, one-bay seismic resistant reinforced concrete framed building under close-in blast loading. ANSYS AUTODYN, an explicit nonlinear finite element software program, was used 3D model development...

The jet morphology of square and circular cross-section shaped charge with same inscribed circle diameter were observed by conducting an X-ray experiment. Depth-of-penetration tests at standoffs 80 160 mm also carried out. formation was studied using AUTODYN software. results showed that the consists a condensed part non-condensed part. has similar characteristics to corresponding charge. And i...
