Аннотация:
Gradient energy-absorbing nature-inspired cellular metamaterial with high energy-absorbing properties has been developed, made from polyamide-12 using selective laser sintering technology. It is shown that the gradient structure provides the effect of "pseudo-plastic failure" due to layer-by-layer deformation of the metamaterial with a significant increase in the energy absorption value, which was 1.88 MJ/m3 for the plastic series, and 1.45 MJ/m3 for the brittle series.
