Molecular dynamics simulations of single-layer and rotated double-layer graphene sheets under a high velocity impact by fullerene

Molecular dynamics (MD) simulations are employed in this paper to study the behavior of single-layer and rotated double-layer graphene sheets under a high velocity impact. The AIREBO force field is used for MD simulations. Stress wave propagation is investigated, and cone-wave and axial-wave velocities are determined. The coefficient of restitution for the double-layer graphene sheet is calculated at different impact incident angles and velocities. Impact and rebound kinetic energy of projectile under the impact simulation of different rotation angles double-layer graphene sheet is monitored. High cone-wave and axial-wave velocities show that single-layer and double-layer graphene sheets have potential applications in impact protection materials.
