Penetration load and energy of a single-layer aluminum sheet coated with a GO solution: (a) load-displacement curves under 3.33 × 10−4 m/s (quasi-static) loading, (b) load-displacement curves under 2.79 m/s impact loading, (c) peak-load and (d) energy dissipation as a function of indentation velocity.
