COMPIMPACT
Characterization and modeling of the impact behavior of a thin-fold composite: towards taking into account the evolution of ballistic protection performance
This thesis investigates the dynamic mechanical response of two high molecular weight polyethylene (UHMWPE) fiber composites, when subjected to ballistic impact.
These very recent grades have been little studied in the literature. The aim is to characterize the mechanical behavior of these materials and identify a model capable of describing the mechanisms observed during an impact. In this thesis, the aim is to propose a simplified, but not simplistic, model of the dynamic mechanical behavior of these materials. In addition, it is planned to assess the impact of the pressing process and material ageing, which are important issues for both the manufacturer and the end-user in order to guarantee a level of performance. With regard to ballistic simulation, the aim is to use the finite element method to simulate the ballistic impact of FSP (Fragment Simulated Projectile) projectiles on a composite plate. The simulation is carried out using LS-DYNA software with an explicit resolution scheme. Finally, the model has been validated by comparison with ballistic tests carried out at Integris composites and ISL.
