Stress wave radiation from brittle crack extension by molecular dynamics and FEM
Keywords:
molecular dynamics, finite element simulation, bcc iron crystalAbstract
We present results for molecular dynamic (MD) and finite element (FEM) 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 MD were chosen in such a way as to invoke a cleavage crack extension. Acoustic emission (AE) sources caused by the crack were analysed on both the atomistic and continuum level with FEM.
