Abstract :
In this paper, molecular dynamic simulations of crack propagation in body centre cubic (bcc) single crystal have been performed. The crack propagation behaviors on two different slip planes ({1 1 0} and {2 1 1}) have been investigated. A self-adaptive time step algorithm has been proposed to increase the stability of the simulations. It has been found that the slip plane significantly affects the propagation speed of the crack.
