Molecular dynamics simulation of perforation of graphene under impact by fullerene projectiles

In this paper, molecular dynamics (MD) simulations are employed to study the perforation of graphene under impact by fullerenes various sizes. The buckling characteristics after classified and discussed. relative state C180 projectile at different velocities is also investigated. We observed that rebounds low velocity (V < 4.25 km/s), sticks high (4.25 km/s ≤ V 4.75 perforates higher ≥ km/s). It found buckled cap large-size fullerene formed can better absorb kinetic energy. addition, crack modes were effect size initial on ballistic limit was clarified. This provides new implications for application as shields.
