Molecular dynamics study of the mechanical behaviour of ultrathin polymer–metal multilayers under extreme dynamic conditions

Recent microprojectile impact tests have revealed that ultra-thin polymer films possess superior specific penetration energy, about ten times more than that of conventional armour materials. On the other hand, it is well established that metallic nanostructures demonstrate extraordinary mechanical properties. Therefore, it may be possible to achieve structures with superior dynamic performance by arranging ultrathin polymer and metal films in...
