An Improved SPH Technique for Fracture Modeling
Abstract
The purpose of the proposed research was to enhance the Smoothed Particle Hydrodynamics (SPH) code named MAGI. With these improvements, the MAGI code could solve the enormously complex problem of simulating Behind-Armor-Debris and subsequent interaction of the spall cloud with threat target components as well as the fragmentation of warheads and other explosively driven devices. The proposed work would have involved several improvements to the numerical implementation of SPH. This was possible, as two of the worlds leading experts in SPH, Larry Libersky and Ted Carney, were employed by NMIMT/EMRTC and both contributed to the proposal. The PI's were intending to add contact and free-surface boundary conditions to the normalized version of MAGI. The one-dimensional case was completed when work was suspended. Unfortunately, by the time the contract was delivered, Larry Libersky had left EMRTC and Ted Carney resigned soon after. There were no other researchers at EMRTC that were competent to complete the contract, so the work was suspended and the contract terminated.
