Original abstract

We present new results of 3D molecular dynamic (MD) simulations of a mechanical response of an edge crack [110] (crack plane/crack front) in a single crystal of bcc iron cyclically loaded in mode II at room temperature and 0 K under different boundary conditions. Our previous 3D molecular dynamic simulations showed that this crack under monotonic uniaxial tension loading in mode I emitted blunting dislocations in the inclined slip systems and it was stable up to very high loads, in qualitative agreement with experiments and continuum predictions. Our question is how the cyclic loading in mode II changes the crack behaviour and its stability. The paper also brings information on comparison with fatigue behaviour of the crack loaded in mode I and in mode III.
