dc.description.abstractOvaj rad predstavlja analitički i numerički pristup procenu performansi brzine za Eksplozivno Formirane Projektile (EFP). Predložene analitičke metode matematički razvijaju parametre brzina pojedinačnih segmenata za EFP disk pogonjen eksplozivnim procesom. Ovaj model baziran je na dobro poznatim teorijskim pristupima distribucije energije na plastičnim telima u dinamičkim uslovima formiranjem integralnih rešenja za konačnu brzinu projektila. Paralelno sa analitičkim takođe je razvijen i numerički metod u cilju obezbeđenja procene ponašanje projktila u toku vrmena procesa formiranja EFP-a pogonjenog eksplozivom. Oba modela su validna za procenu performansi EFP bojevih glava i projektnih podatka za optimalno projektivanje oblika EFP-a. Simulacije su podržane softverima Matlob i Autodin kako za ananlitičko tako i numeričko modeliranje. Dobijeni numerički i analitički rezultati upoređeni su sa raspoloživivim eksperimentalnim rezultatima. PR Projekat Ministarstva nauke Republike Srbije, br. III-47029.sr
dc.description.abstractThe current paper presents analytical and numerical approaches of velocity performances estimations for the EFP (Explosively Formed Projectiles). The proposed analytical methods mathematically develop velocities parameters of a particular segment for EFP liner propelled by explosive process. This model is based on the well-known theoretical approaches of energy distribution on plastic body in dynamical conditions providing integral solution for projectile final velocity. The redundant to analytical, the numerical method is also developed, to provides estimations about behavior of projectile vs. time in the EFP forming process powered by explosion. Both models are valid for performances estimations of EFP warheads and design data for optimal EFP configuration. Simulations are supported by the software Matlab and Autodyn for analytical and numerical modeling respectively. The obtained numerical and analytical results are compared with the available experimental data.en
