Abstract
For a feasibility study of plastic working at nanometer level with higher production efficiency and lower costs, molecular dynamics computer simulations of nano–drawing and nano–bending of monocrystalline copper wore carried out. .The results show that, in nano–drawing, stable drawing can be possible with the die the diameter of which is larger than 6.28nm. However, in case of nano–bending, the dislocations generated during loading process disappear from the specimen surface during unloading process. As a result, permanent deformation does not occur. To realize the nano–forming by plastic deformation, heat reatments before unloading are inevitable.
