Impact Effects in Multilayered Plates

Abstract

This report presents results of numerical simulations of impact effects in monoblock and multilayered plates using both Lagrangian and Bulerian wave propagation codes. It is found that lagrangian simulations compare favorably with experimental and analytical results. Eulerian codes, while ideal for large distortion situations such as penetration, have great difficulty in describing multiplate perforation due primarily to problems with the interface treatment in Eulerian codes. This report was originally presented as a paper at the Special Symposium Honoring the 70th Birthdays of Professors Jack Vinson and Charlie Bert, which was part of the 1999 ASME International Mechanical Engineering Congress and Exposition held in Nashville, TN, on 14-19 November 1999. The paper has been accepted for publication in a special volume of The Journal on Solid and Structures.
