“…The contact radius was determined using both the Greszczuk [12] equations and the Dahan and Zarka [13] equations. The latter have typographical errors that were reconciled using the limiting case of an isotropic half- Several disastrous attempts at analyzing the impact site model, Figure 13, were made using CCC elements for the upper plies and CCL elements for the subsurface laminate model.…”

Materials. The materials used in this research were T300/5208 unidirectional graphite/epoxy composite panels supplied by the Army Materials Technology Laboratory. The panels were in square form of 12 in. by 12. in. with nominal thicknesses of 0.042 in. (7-ply) and 0.144 in. (24-ply) respectively. All of the panels were subjected to c-scan examination for uniformity and integrity. The properties of the material are presented in Table 1. A schematic of the unidirectional composite is shown in Fig. 1.
