Optimisation of ballistic protection systems based on impact test/simulation correlation [PDF]

EPJ Web of Conferences, 2021
The complexity of ballistic protections increases with their efficiency. On this basis, an exclusively empirical approach is not adapted to optimise complex protection systems and the resort to numerical simulations is preferred if not mandatory. The present study proposes a methodology aiming at optimising complex multi-layer ballistic armours based ...

A model of ballistic aggregation and fragmentation [PDF]

, 2009
A simple model of ballistic aggregation and fragmentation is proposed. The model is characterized by two energy thresholds, Eagg and Efrag, which demarcate different types of impacts: If the kinetic energy of the relative motion of a colliding pair is ...

Extraordinary impact resistance of carbon nanotube film with crosslinks under micro-ballistic impact

, 2021
The crosslinks of carbon nanotubes (CNT) film has been demonstrated to owing the ability to reinforce the quasi-static mechanical properties. But it is unclear whether crosslinks improve the ballistic impact resistance of CNT film.
