Abstract

This study investigates how the Eulerian hydrocode PAGOSA performs while simulating a hypervelocity impact experiment of stainless steel 304-L into aluminum 6061-T6. The specifications of the simulation were established in a paper detailing an experiment conducted at the Atomic Weapons Establishment (AWE) in the UK and the Centre d’Etudes de Gramet (CEG) in France. A variety of strength models and equations of state are employed under several different mesh sizes. The results display an excellent comparison with the experimental data and demonstrate dramatic differences in impacted crater geometries over various strength models and mesh sizes.

Modeling Plastic Deformation of Steel Plates in Hypervelocity Impact Experiments

Conference O?Toole, Brendan ; Trabia, Mohamed ; Hixson, Robert ; ... - Procedia Engineering

Hypervelocity impact experiments were done with a two-stage light gas gun to study the plastic deformation of metallic plates. Cylindrical Lexan projectiles were fired at A36 steel target plates with a velocity range of 4.5-6.0 km/s. Experiments were designed to produce a front side impact crater and a permanent bulging deformation on the back surface of the target while preventing complete perforation. Free surface velocities from the back surface of target plate were acquired using the newly developed Multiplexed Photonic Doppler Velocimetry (MPDV) system. Two different computational techniques were developed to simulate this type of experiment: Lagrangian-based smooth particle hydrodynamicsmore »« less

Numerical Simulation of Interaction of Hypervelocity Particle Stream with a Target

Conference Lomov, I ; Liu, B ; Georgevich, V ; ...

We present results of direct numerical simulations of impact of hypervelocity particle stream with a target. The stream of interest consists of submillimeter (30-300 micron) brittle ceramic particles. Current supercomputer capabilities make it possible to simulate a realistic size of streams (up to 20 mm in diameter and 500 mm in length) while resolving each particle individually. Such simulations make possible to study the damage of the target from synergistic effects of individual impacts. In our research we fixed the velocity distribution along the axis of the stream (1-4 km/s) and volume fraction of the solid material (1-10%) and studymore »« less

The simulation of 3D hypervelocity spallation using a hydrocode PAGOSA with FLIP+MPM

Journal Article Ren, Jinlian ; Ma, Xia ; Smith, Brandon ; ... - International Journal of Impact Engineering

n this work, a hydrocode PAGOSA with FLIP+MPM is presented and exercised to investigate the fracture in ductile material. The merit of PAGOSA with FLIP+MPM to solve the advection problem is first illustrated by a solid piston periodically moving in a sealed tube with air. Furthermore, the ability of PAGOSA with FLIP+MPM to capture the fracture in material is shown by a simple stretching fracture in ductile material. In both of two benchmark problems, the PAGOSA results and analytical solutions are also presented for comparison. Then PAGOSA with FLIP+MPM is used to model complex spall in ductile material, which ismore »« less

Simulation of hypervelocity impact on massively parallel supercomputer

Conference Fang, H E

Hypervelocity impact studies are important for debris shield and armor/anti-armor research and development. Numerical simulations are frequently performed to complement experimental studies, and to evaluate code accuracy. Parametric computational studies involving material properties, geometry and impact velocity can be used to understand hypervelocity impact processes. These impact simulations normally need to address shock wave physics phenomena, material deformation and failure, and motion of debris particles. Detailed, three-dimensional calculations of such events have large memory and processing time requirements. At Sandia National Laboratories, many impact problems of interest require tens of millions of computational cells. Furthermore, even the inadequately resolved problemsmore »« less

Multi-dimensional hydrocode analyses of penetrating hypervelocity impacts.

Conference Saul, W Venner ; Reinhart, William Dodd ; Thornhill, Tom Finley, III ; ...

The Eulerian hydrocode, CTH, has been used to study the interaction of hypervelocity flyer plates with thin targets at velocities from 6 to 11 km/s. These penetrating impacts produce debris clouds that are subsequently allowed to stagnate against downstream witness plates. Velocity histories from this latter plate are used to infer the evolution and propagation of the debris cloud. This analysis, which is a companion to a parallel experimental effort, examined both numerical and physics-based issues. We conclude that numerical resolution and convergence are important in ways we had not anticipated. The calculated release from the extreme states generated bymore »« less
