Computer Simulation of Scaled MARK 84 Bomb Impact into Concrete
This report presents the results of three-dimensional finite element analyses of a scaled (1/15) MK84 bomb impacting thick concrete targets at large obliquities. Two bomb structures were modeled, one of solid steel and another with an 0.2cm steel wall, the cavity being filled with an inert simulant...

| description | This report presents the results of three-dimensional finite element analyses of a scaled (1/15) MK84 bomb impacting thick concrete targets at large obliquities. Two bomb structures were modeled, one of solid steel and another with an 0.2cm steel wall, the cavity being filled with an inert simulant to represent the explosive tritonal. The analysis covers the latter one. The computations were performed with EPIC-3, a three-dimensional finite element program for the study of wave propagation and impact in homogeneous isotropic and anisotropic materials, as well as concrete. The critical impact angle for delineating penetration and ricochet is determined as a function of bomb structure and obliquity. These prove to be in close agreement with experimental results. Some comments on computational approaches for rapid, cost-effective numerical studies of such situations conclude the paper. |
