A representative volume element (RVE) based multi-scale method is proposed to investigate the mechanism of fatigue crack propagation by molecular dynamics (MD) and extended finite methods(XFEM) in this study. An atomic model carbon steel plate built study behavior at micro scale MD method. Then RVE for should be fitting data which was obtained from result with Paris law model. Moreover, effect ...

Abstract Steel fiber reinforced concrete (SFRC) will appear ununiform corrosion under chloride environment, resulting in corrosion-induced crack. However, the mechanism of crack corroded SFRC is not clear. In this paper, 3D mesoscale numerical model structure established, generation algorithm round straight steel provided, and are simulated by XFEM, at end damage characteristic studied. The res...
