Abstract: The research covered in this paper is related to the numerical modelling of explosively formed projectiles (EFP). In-depth literature reviews on both the physical characteristics and simulation of this weapon are given. Results from a numerical model of an EFP are compared with experimental data showing good correlation. All models ran successfully to normal termination. They showed how numerical tools can be used to describe and investigate these very complicated events involving large deformation and extremely high strain rates. Further, a sensitivity study is carried out on the location of the detonation point, the number of smoothed particle hydrodynamics (SPH) particles, type of high explosive (HE) as well as a test case where the casing is not modelled.
