Abstract In order to study the damage effect of blast-killing warhead on steel target at different falling velocities and angles, AUTODYN-3D software was used numerically simulate velocitis angles using SPH algorithm. The results show that hole shape plate is quadrilateral when angle 0°, round 90°, circular fan-shaped 30° 60°. At same angle, area increases with increase velocities. velocities, ...

This paper presents numerical analysis result of forming characteristics of Ta explosively formed penetrator (EFP) according to various material models and their values. Dynamic material properties of Ta were measured with static tensile testing machine and Hopkinson pressure bar tests. We used AUTODYN hydrodynamic code to simulate these phenomena. We used three material models, such as Von-Mis...

Abstract In order to study the formation and penetration performance of reactive liner, in this paper, a Ta-Zr alloy is used as liner material, large cone angle spherical arc-cone are simulated analyzed by using AUTODYN software. The following conclusions obtained: (1) EFP formed has good flight stability, followed arc liner; (2) length diameter ratio shaped charge larger than that (3) depth la...

Materials blasted into space from the surface of early Earth may preserve a unique record of our planet's early surface environment. Armstrong et al. (2002) pointed out that such materials, in the form of terrestrial meteorites, may exist on the Moon and be of considerable astrobiological interest if biomarkers from early Earth are preserved within them. Here, we report results obtained via the...

Abstract To study the damage of shock vibration generated by ship hull to internal equipment under secondary explosion impact, a three-dimensional simulation model BE rubber isolator was established. The signal impact load loaded AUTODYN software. And relationship between primary and frequency, amplitude, attenuation loading found. It is revealed that law curve conforms rational function. Based...

The object of research is the processes pulse explosive loading in an explicit formulation for simulation complex nonlinear dynamics solids, gases, and their interactions. One most problematic areas modern studies dynamic loads materials using a numerical analysis that such usually do not take into account characteristic transition stationary deformation zone loaded material to unsteady one fro...
