AB  - Osnovni cilj ovog istraživanja je izrada numeričkog modela oštećenja vozila pod dejstvom eksplozije mine, kao i pronalaženje najpovoljnijeg slučaja geometrije V-trupa i ukazivanje na moguće rešenje za ublažavanje efekata eksplozije mina na oklopno borbeno vozilo. U obzir je uzeto sedam različitih geometrija V-trupa i izvršena je analiza oštećenja strukture za svih sedam mogućnosti. Takođe, analizirana je i promena mase za različite geometrije. Efekat eksplozije mina na ciljnu strukturu analiziran je korišćenjem funkcije natpritiska prema empirijskom modelu CONWEP, korišćenjem programa Abaqus/Explicit. Analiziran je primer eksplozije 8 kg eksplozivne materije Kompozicija B koja deluje na vozilo ukupne mase 8000 kg. Vozilo se sastoji od dva glavna dela - kabine mase 6 t i V-trupa mase 2 t. Trup u obliku slova V je u svim prikazanim primerima sačinjen od ploča debljine 10 mm izrađenih od čelika Hardox 400. Položaj eksplozivnog punjenja je za sve primere geometrije isti i nalazi se 0.6 m ispod centra vozila. Nakon analize dobijenih rezultata utvrđena je najpovoljnija geometrija V-trupa i ukazano je na mogućnosti daljeg unapređenja numeričkog modela.
AB  - The main objective of this research is to develop a numerical model of vehicle damage caused by an explosion of a mine, as well as to find the most favorable case of V-hull geometry and to point out a possible solution for mitigating the effects of mine explosion on an armored vehicle. Seven different V-hull geometries were considered and structure damage analysis was performed for all seven options. Also, the mass change for different geometries was analyzed. The effect of the mine explosion on the target structure was analyzed using the overpressure function according to the empirical CONWEP model, using Abaqus / Explicit software. An example of an explosion of 8 kg of Composition B acting on a vehicle with a total mass of 8000 kg was analyzed. The vehicle has two main parts - the cabin with mass of 6 t and a V-hull of mass of 2 t. The V-shaped hull in all the examples shown is made of 10 mm thick plates of Hardox 400 steel. The position of the explosive charge is the same for all geometry examples and is 0.6 m below the center of the vehicle. After analysis of the obtained results the most favorable V-hull geometry is determined. The guidelines for the further work and model improvement are suggested.

AB  - The main objective of the present research is development of a preliminary numerical model
of dynamics and possible damage of a vehicle under the action of blast wave generated by the
activation of a landmine. Such a model should provide a valuable insight into complex
phenomena accompanied by detonation of a mine – pressure distribution in time, vehicle motion,
damage, etc. Numerical simulation has been performed using Abaqus/Explicit, FEM-based
software suitable for nonlinear processes with high strains, strain rates and energy densities,
which is typical for explosion effects. A representative case study of an explosion of 8 kg
explosive substance Composition B was analyzed. The explosion takes place under a vehicle with
the mass of 8 tons, with specific V-shaped body consisted from 10 mm thick armor steel plates.
The numerical model based on usage of Abaqus build-in CONWEP blast relations is described.
The results obtained show the displacement, and stress-stain field in the loaded vehicle, on the
basis of which the degree of damage to the target structure can be predicted. The guidelines for
the further work and model improvement are suggested.
