Finite element simulations and experiments of ballistic impacts on high performance PE composite material
conference paper
The use of lightweight composite armour concepts is essential for the protection of future combat systems, both vehicles and personal. The design of such armour systems is challenging due to the complex material behaviour. Finite element simulations can be used to help understand the important design parameters. A material model of Dyneema, a high performance poly-ethylene (HPPE) composite, has been developed with the use of Autodyn. This model is used in several projectile-target configurations and the results are compared to experiments. The simulated residual velocities correspond to the experimental velocities. Also the penetration depths into the target correspond to the experiments when the projectile is stopped. Comparison of the deformation of the backface of the target is difficult due to the long run times necessary to reach the final deformation. However, the first findings are very promising.
