  Advanced manufacturing (AM) technologies, such as nanoscale additive
manufacturing process, enable the fabrication of nanoscale architected
materials which has received great attention due to their prominent properties.
However, few studies delve into the functional gradient cellular architecture
on nanoscale. This work studied the gradient nano-Gyroid architected material
made of copper (Cu) by molecular dynamic (MD) simulations. The result reveals
that, unlike homogeneous architecture, gradient Gyroid not only shows novel
layer-by-layer deformation behavior, but also processes significantly better
energy absorption ability. Moreover, this deformation behavior and energy
absorption are predictable and designable, which demonstrates its highly
programmable potential.
