Three-Dimensional Modelling and Simulation of Ballistic Impact
Abstract
The overarching theme of the work originally proposed concerned the development of three-dimensional computational capability enabling the lagrangian simulation of armor penetration. The principal objectives of the work, as stated in the proposal, were: (1) The development of three-dimensional computational capability including adaptive meshing, direct simulation of fracture and fragmentation by cohesive elements, nonsmooth contact and friction. (2) Verification and validation of the unit algorithms. (3) The demonstration of the predictive ability of the integrated facility in problems of ballistic penetration of interest to the Army. All the unit algorithms required to carry out the simulations of interest in three dimensions have been developed and successfully tested. The degree of difficulty involved in the development of these algorithms vanes from low (e.g., the extension of the constitutive updates to three dimensions) to exceptional high (most notably, the development of automatic 3D meshing capability for arbitrary domains). Some of the main accomplishments are summarized next.
