Despite having the highest resistance to impact as seen by its high rate of energy growth over time, it eventually buckles under load and deforms to a state where the structure indicates that failure has occurred. When looking at the other cases, the 16-unit case presents the best combination of resistive force (Fig. ), stress intensity, and energy absorption. The results for the cases between 4-14 units show minimal variation, indicating that within that range, there is not much difference in terms of these factors.
