One of the most endangering and challenging threats during recent warfare are explosions of Improvised Explosive Devices (IED) and their destructive influence on a light armoured vehicle. Providing sufficient protection is the most challenging issue which can be achieved thanks to complex studies and a proper design process. The article presents preliminary numerical analyses of side explosion near a special military vehicle with regards to newdeveloped standards. The results were used to modify the existing hull and enhance its protection capabilities against critical charge to provide better protection for personnel inside the vehicle. A numerical model was developed in LSPrePost software. All the computational analyses were carried out using an explicit LS-Dyna solver, where material properties of finite elements were described by the Johnson-Cook material model with the basic parameters specified in the standard tensile tests. Due to time consuming simulations, the Linux-based computational cluster was adopted. The setup (mass of the explosive, distance between explosive charge and vehicle, etc.) was taken from military codes. In their computational research, the authors performed also a kind of a sensitivity study changing some of parameters. Pressure, stress distribution and plastic deformations vehicle structure were analyzed.
