There are longstanding interests in multi-material shaped charge liners for purposes of, for example, diagnosing jet formation, overcoming coherent flow limitations, and enhancing behind the target effects. This research shows the possibilities for generating stable multi-material coaxial shaped charge jets. General design criteria and guidelines for multi-material coaxial jetting and penetration are developed and investigated, based on experimental data and simulation of a 100 mm charge. Further, the influence on jet coherency and the effect of density variation on penetration is studied. Findings are in agreement with Harisson's and Walker's coherency theory, showing that the flow velocity is the key factor for jet coherency. Multi-material design concepts are presented and tested with the finite difference code ANSYS AUTODYN |
