The study presents new results of 3D molecular dynamic simulations of a mechanical response of an edge crack (001)[110] (crack plane/crack front) in a single crystal of bcc iron cyclically loaded in tension mode I and shear mode II at room temperature. Different boundary conditions were tested for mode II. We compare fatigue behaviour of the crack (001) loaded in mode II and I with behaviour of a ductile crack [110] recently studied. The paper brings new information on micromechanism of fatigue crack growth.
