Keywords: composite materials, fasteners, impact, simulation

Fastener models available in commercial explicit finite element codes suitable for impact and crash simulation have been evaluated. The stiffness and strength characteristics of aircraft-representative fastened composite joints were modelled and compared to experimental data. Preliminary results showed good agreement between test and simulation.
