The article presents numerical simulation of interaction of a pressure wave coming from detonation of an improvised explosive device on the crew of the ligtharmoured wheeled vehicle. There was analysed one of the typical scenario, namely the explosion on the side of the vehicle, which the army deals with during the stabilization missions of different kind. The objective of the presented numerical investigations was to examine the influence of dynamics impulse, according to mass of detonated charge, on the crew in the characteristic anthropometric points of the body. The numerical investigations presented in the present paper aimed at testing the influence of the mass of the detonated charge on the load to which the vehicle crew is subjected to. In order to meet this target, there were used capability of coupling between the compressed air, described with the use of equations of continuum mechanics by Euler, and the vehicle with the crew described with the same equations but formulated by Lagrange. Interaction of both of the centres was executed with the use of general coupling. To perform the analyses, Ls-Dyna software based on the finite element method with the algorithm of explicit integration in time was used. Development of a full-scale model of the special vehicle was preceded with the laboratory tests on the mechanical properties of armour steel applied for constructing the vehicles of this type.
