摘要：

The paper presents results of molecular dynamic (MD) simulations in 3D bee iron crystals with edge pre-existing cracks (001)[110] and ((1) over bar 10) [110] (crack plane/crack front) loaded uni-axially in tension mode I at temperature of 300 K. The iron crystals in MD have the same orientation and similar geometry as in our recent fracture tests performed at room temperature on iron (3wt.%Si) single crystals [1].
