Digital Image Correlation: Visualizing Strain Evolution and Coordinated Buckling within CNT Arrays by In Situ Digital Image Correlation (Adv. Funct. Mater. 22/2012)
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.
