Energy absorption during projectile perforation of lightweight sandwich panels with metallic fibre cores

Energy absorption during ballistic impact is of vital and primary significance in armour design. Advanced sandwich plate-based armour with metallic fibre cores was designed, manufactured, modelled and tested, improving understanding of perforation mechanisms. Material constitutive behaviour for the core was developed within the framework of dilatational plasticity and implemented through user defined constitutive models. Proposed armour has the best performance among alternatives on equal weight basis and is of real benefit to the defence industries as it provides a lighter system and ultimately helps save lives through improved safety (Dstl scientist: Peter Brown - pmbrown@dstl.gov.uk).
