Stress wave radiation from the cleavage crack extension in 3D bcc iron crystals

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.
