FATIGUE ANIM GIF 2

Caption

Rice University researchers determined several ways a nanotube experiences plastic failure, either through dislocation movement under 6% strain or in this animation through shear band formation under 14% strain. Both mechanisms, seen in kinetic Monte Carlo simulations, only activate under extreme conditions, so neither appears to be a significant factor in fatigue of the nanotubes.
