    Dislocation simulation of brittle-ductile transition in ferritic steels

    Two-dimensional discrete dislocation simulations of the crack-tip plasticity of a macrocrack-micro-crack system representing the fracture behavior in ferritic steels are presented. The crack-tip plastic zones ...

    A Multiple Slip Plane Model for Crack-Tip Plasticity

    A single slip plane dislocation dynamics based model for the brittle to ductile transition has been extended to have multiple slip planes around the crack-tip. The crack-tip plastic behaviour is studied for a ...
