Abstract
Many researches using the molecular dynamics method have been made recently. About the dislocation which has many relation in plastic deformation of metal, writers analyze using a molecular dynamics method, and perform comparison with the dislocation theory on the basis of continuation physical strength study. It is made to move to the border plane which applied external force to the α-Fe crystal with two or three edge dislocation, and is fixed to it, and the simulation of dislocation pile-up is tried. Moreover, comparison with this result and Eshelby's dislocation pile-up theory is performed.
