The preliminary results from parallel molecular dynamics (MD) simulations will be presented for fracture dynamics of two dimensional notched Lennard-Jones solid under tension using 39984 atom system. For the MD simulations, a parallel code has been developed using spacial decomposition method and tested on linux cluster up to 512 CPU's. The effects of defects on fracture dynamics will be addressed from the comparison of the fracture dynamics between perfect crystal and defected crystal. In particular, how crack propagates in the defected crystal compared to the perfect crystal will be discussed in this presentation. |
