Book excerpt: Three dimensional simulation of oblique hypervelocity impact on orbital debris shielding places extreme demands on computer resources. Research to date has shown that particle models provide the most accurate and efficient means for computer simulation of shield design problems. In order to employ a particle based modeling approach to the wall plate impact portion of the shield design problem, it is essential that particle codes be augmented to represent strength effects. This report describes augmentation of a Lagrangian particle hydrodynamics code developed by the principal investigator, to include strength effects, allowing for the entire shield impact problem to be represented using a single computer code.Fahrenthold, Eric P.Johnson Space CenterHYDRODYNAMICS; THREE DIMENSIONAL MODELS; OBLIQUE SHOCK WAVES; HYPERVELOCITY IMPACT; SPACE DEBRIS; AUGMENTATION; COMPUTERIZED SIMULATION; COMPUTER PROGRAMS; WALLS; MECHANICAL PROPERTIES; DESIGN ANALYSIS
