Movie S1
In-situ compression video (played at 40x speed) of a thin-walled nanolattice (5µm unit cell, 10nm wall thickness, t/a = 0.0133) to ~40% strain. Deformation is homogenous and localized to shell buckling events near the nodes. The nanolattice demonstrates almost complete recovery after compression.
Movie S2
In-situ compression video (played at 40x speed) of a nanolattice in the transition regime between thin- and thick-walled (5µm unit cell, 20nm wall thickness, t/a = 0.0233). The nanolattice is compressed to ~55% strain. It can be seen that strain bursts are associated with brittle failure events, and ductile-like deformation coincides with local buckling in the beams. The nanolattice partially recovers after compression.
Movie S3
In-situ compression video (played at 20x speed) of a thick-walled nanolattice (5µm unit cell, 60nm wall thickness, t/a = 0.0667). There is a single strain burst event to ~85% strain correlating with the catastrophic failure of the nanolattice, and no subsequent recovery after compression.
