FATIGUE ANIM GIF 1 (IMAGE) Rice University Caption Rice University researchers determined several ways a nanotube experiences plastic failure, either through dislocation movement under 6% strain (here) or 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.
