Digital image correlation is used for the first time to measure the spatially resolved strain evolution of compressed carbon nanotube columns. A consistent local critical strain criterion of 5% is discovered, unifying otherwise disparate column behavior. As reported by Jeffery W. Baur and co‐workers on page 4686 , this new capability enables the visualization of the inhomogeneous deformation inherent in many nanoscale and microscale materials.
