The cover picture shows a jet of material that was observed exiting from the rear of the remnants of an initially semi‐hollow copper explosively formed projectile, which perforated a finite thickness composite armour panel. The jet exhibited remarkably similar characteristics to what is typically observed for shaped charge jets of similar liner materials. Simulation of such an event by the ANSYS Autodyn hydrocode showed that reverse jet formation is possible for specific EFP geometries and impact conditions. Details are discussed in the article by Izak Snyman et al. on page 194 ff.
