Abstract:

This report examines various computational approaches for projectile impact onto concrete targets. Included are two- and three-dimensional computations performed with both the Epic-2 and Epic-3 codes. Various techniques, such as tunneling, eroding, and NABOR nodes, are used to compare results and demonstrate capabilities. Results are presented for normal, oblique, and yawed impact. This report also documents the NABOR algorithms for axisymmetric and three-dimensional geometry. These NABOR algorithms allow for variable nodal connectivity and are well suited for projectile-concrete impact problems.
