| The buckling process of a typical buckliball. (The colors represent stress.) The buckling motion consists mainly of counter-clockwise rotation of the narrow triangular-like portions with local bending of the narrow ligaments, which result in the closing of the apertures and the decrease in diameter of the deformed buckliball. |
