With the increase of number of space debris and satellites in low-Earth orbit, the vulnerability of the solar panels fitted to these satellites is becoming a major issue. In this context, CEA-Liten is developing new solar panel solutions featuring advanced flexible materials which could be used for Z-folded or rollable photovoltaic Assembly (PVA). The aim of this PhD project is to study the impact and post-impact behaviors of these new solar PVA under hyper-velocity impact of millimeter-sized projectiles. To this end, the IDL and CEA and 3SR laboratories are proposing to develop a strategy based on the following steps: identification of loading-rate and pressure levels through a series of numerical simulations, characterization of the mechanical behavior of materials and interfaces involved in solar PVA by means of high strain-rate testing thanks to Hopkinson bar and plate-impact experiments, identification of equation of states and damage and fracture constitutive models and their implementation in numerical codes, predictions of damage and fracture in PVA subjected to hyper-velocity impact and comparison with experimental data by means of impact tests consider a large range of impact speeds.
