We present results for molecular dynamic and finite element simulations in 3D bcc iron crystals, with embedded central through crack (001)[110] of Griffith type, loaded in mode I. The sample geometry and border conditions in molecular dynamics were chosen in such a way as to invoke a cleavage crack extension. Acoustic emission sources caused by the crack were analysed on both the atomistic and continuum level with finite element simulations.
