The paper presents results obtained through numerical simulation on the deformation, failure point, of polylactic acid (PLA) polymer after applying collision load. This research explored the influence density of samples had on energy absorption of polylactic acid, as well as the relationship between the velocity of the collision load and deformation. The numerical analysis by ABAQUS / Explicit 6.16.1 program for lactic acid polymers and the difference in velocity parameters was addressed. The absorbed energy was obtained by ABAQUS / Explicit 6.16.1, and its properties were evaluated to reduce the shock. The results showed that the PLA failure point was at the highest velocity 7.5 m/s where the absorbed energy is 98.43 J. The impact of commercially available coat heights, density, and fill patterns on the PLA power dissipation properties were assessed. The ability to absorb shocks was strongly dependent on bulk density, in terms of reduced impact and energy dissipation.
