Abstract: This paper presents the development of a multi-scale simulation process for modelling the response of a vehicle with composite armour to the blast loads from an explosive threat. The new process can be used for improving the blast resistant capabilities of the composite armour by configuring its properties at the micro-level. A Blast Event Simulation sysTem (BEST), for conducting a complete sequence of explosive simulations, comprises one of the two main foundation components of the new development. The Micromechanics Analysis Code (MAC) comprises the second main foundation component. The development of the new multi-scale simulation capability and an associated case study are presented.
