Abstract
We hereby present new results for molecular dynamic (MD) and finite element (FEM) simulations in 3D bcc iron crystals, with embedded central through crack (0 0 1)[1 1 0] of Griffith type, loaded in mode I. The sample geometry and border conditions in MD were chosen in such a way as to invoke a cleavage crack extension. The stress field and acoustic emission sources caused by the crack were analysed on both the atomistic and continuum level.
