A molecular dynamic study of nano-grinding of a monocrystalline copper
A grinding depth of 1.5 nm shows more distinct characteristics of the Cu thickness. When the grinding depth was increased by 5 Å, the Shockley dislocations lengthened by 47.0 nm in the 4.3-nm Cu layer. Conversely, the changes in Shockley dislocations were much smaller for the 2.2- and 6.1-nm Cu layers.
