Energy absorption mechanisms of nanoscopic multilayer structures under ballistic impact loading

Our latest article on the ballistic performance of polymer/metal nanostructures is freely available for 50 days from today: https://authors.elsevier.com/a/1cy9c3In-urcWx

Our nanoscale simulations demonstrate that a polymer layer on the strike face is more effective in mitigating impact-induced damage. A polymer layer on the back face is weakened by the shock wave reverberation. During the perforation, a nanoscopic projectile experiences two substantially different levels of resistance due to the interaction between the incident projectile and the tensile release wave. The shock pressure and adiabatic heating of polymer films significantly increase as the film thickness decreases.
