In this paper the results of computer simulation of blast wave action arising from mine or IED explosion on wheeled light armoured vehicle will be presented. In the last years the NATO STANG 4569 international standard has been prepared. It describes the test standards concerning the ballistic resistance of vehicles not only to missiles but also to fragments and pressure wave arising from mine or IED explosion. In accordance with this standard the explosive charge is placed under ground surface (independently to the charge position in relation to the vehicle-under the wheel or under the vehicle centre). This case is of frequent occurrence during the different stabilization missions conducted by our troops both in Iraq and in Afghanistan. In the calculations the possibility of coupling between the medium described with the aid of Eulerian equations and the medium described with the aid of Lagrange equations has been used. The coupling enables the complex description of the issue. The detonation process has been described approximately of detonation optics and the behaviour of detonation of explosive device has been described with the aid of JWL equation in common use. Such approach to the subject is sufficient to resolve mast engineer problems. The vehicle has been described with the aid of Lagrange elements with corresponding material properties. The effect of high masses has been taken into account, in particular the effect of engine on behaviour of the object. The adequate coupling of the mediums above- mentioned has been very difficult during the numerical work, but additional taking the ground in consideration has improved considerably the quality of the results obtained which are nearer of the real results.
