Ballistic impact of a projectile on soft fabrics assemblies is a complex process which is important to understand in order to optimise the performance of the fabric assembly. Ballistic testing has been one of the major means to investigate the energy absorbing mechanism of the fabric assemblies but the amount of data is only limited due to methods used for data acquisition which is currently available. This paper describes a finite element method used for modelling the ballistic impact process and the simulation under different circumstances. Geometric modelling of fabrics and projectile, establishment of the FE model, and data analysis will be explained and the results have led to further understanding of the nature of impact between a rigid projectile and a flexible textile assembly. Useful conclusions are drawn for body armour engineering.
